I have not read this thread Ipse...

But

If you sue this therapist... your chances of finding new therapists narrow quite a bit...and talking about your litigation with the therapist you are seeing... is just bad karma. It would also prolong the pain to litigate. Talk about beating a dead horse.. this can take YEARS.

As for closure... She called you. You had the opportunity to ask questions. She is done.

JMO I am sorry for your loss...and know you are grieving.
