Hey yeeter,
I feel for you. It's really painful when a beloved child shuts down. The dad/daughter connection is so important, too.
wife had latched into middle child as her favorite and controlled everything about her activities.
DH's xW and her husband (stepdad) made SD14 (oldest) the golden child. She was "wise beyond her years, insightful, amazing, advanced, just like Mom" etc. Lots of flattery and "specialness" and connection. They elevated her above DH to a position for her to judge his parenting (dysfunctional inverted triangle, I think). That was from ages 6 to 10-ish.
Long story short, it is possible to regain a connection with kids who have been put in that position. SD14 loves spending time with DH now. It took a couple years of counseling (which, interestingly, SD14 says "didn't work") plus DH really rolling with a lot of the anger and emotion coming from SD14, and not taking it personally.
There is still a lot of painful stuff coming from SD14 to DH, but she's not outright refusing to spend time with him like she used to, or being defiant, isolating, or rejecting. Really wants warm, close times. So, it's hard now, yet not impossible for things to change.
I was able to get some communications with her counselor. So hoping that helps. And I am pushing for family counseling with the courts (and reconciliation counseling with her if I can get it, wife opposes)
Really good idea. Be consistently relentless at making this happen.

Recently there has been some false allegations started. For sure all three are hearing various things about how terrible their father is as a person.
Have you already looked at Dr. Craig Childress' work on dysfunctional family systems? He has incredibly helpful, non-intuitive, defusing techniques for times when the kids spout at you "everyone knows you're selfish" type stuff. He subtitles this article "strategies to disarm false reality":
https://drcachildress.org/wp-content/uploads/2019/11/Ju-jitsu-Parenting-Fighting-Back-from-the-Down-Position-Childress-2013.pdfIt helps preserve the relationship, and take the teeth out of the false statements, without going down the unhelpful rabbit trail of defending yourself. Basically, when the kids come to you with something like "Mom says you never did what she wanted when you guys were married", what's going on is: Mom wants to engage you in a drama triangle, and she is using the kids to rope you in. The kids want to know what's true, but just telling them straight up "That's not true, I always made sure we went where Mom wanted to go on vacation" is actually playing the role that Mom wants you to play, and is playing it out in front of the kids.
You see, what the kids want to know isn't the content (did you or didn't you go on vacation where Mom wanted). What they want to know is the structure of how the family is organized: Is Mom really a victim? Are you really a bad guy/persecutor?
When we get blinders on and focus on the veracity of the content, we play into the drama triangle, which unfortunately answers the kids' question in the way Mom wants: See, Dad just argues with Mom and says she's a liar. Now we know Mom was the victim and Dad was selfish and mean.
We have to sidestep the triangle entirely, by bypassing the bait (the content), in order to not play into the structure.
It has taken me a LONG time to start seeing these triangles. One insight I had recently is that any time I find myself wanting to explain myself or DH to the kids, or explain "that's not what happened", there is probably a triangle involved, and the minute I engage with the content of the triangle, I've already lost. Mom and Stepdad are pros at trying to force DH and I to play in the roles they want to cast us in (DH is selfish and self centered and an abandoning abuser, kells76 is an irrelevant adult child who is not important to the family). The key is to jiu-jitsu out of the triangle by not meeting force with force, but typically with another question. LnL has helped me a lot with these key phrases:
"Huh, I wonder why Mom [or whoever, or "someone"] would say that"
"Seems kind of awkward for someone to say what kind of person I am"
"Heh [with a low key smile]... well, I know what I've always thought and felt, and that's good enough for me"
"What do you think about that?"
"What was it like for you to hear that?"
...
Well, THAT was a lot that just came out.
I make her some chili from time to time, her favorite food and she must eat it because the containers come back empty. And send the emails. Occasional text about something she might be interested in. Just keep pushing stuff even if one direction.
Yeah, I think that's the right move. It's so important for kids to know that they don't have to act/be a certain way to be able to count on your love and attention. She doesn't have to "be loving back to you" or respond at all in order to know she can always count on your care. This is a big deal. Don't ever let your actions be dependent on how she engages with you. So critical, and you're doing the right thing here.
Keep on for the long haul... it can get better.
