Yes, a break from the Pitt cult for the sufferer may be advisable, it destroys her relationships and indoctrinates her in fatalism, radicalizes her against the world and freedom. Get actual professional counselling and try to understand the other person, instead of asking the world to demonize and reform her.
It's interesting, about the chat bot, if true, it's not impossible that it "refused" to formulate things the way she hoped. From what I noticed when doing tests with it, it's mostly a mirror with a database that tends to repeat in other words what we tell it, may come out with errors, pretends to understand when corrected, then often inserts a particular conclusion when topics are controversial. That conclusion is often opiniated itself and to attempt not to be, tends to push a "journalistic false balance". For instance, I had to remind it that there was a difference between actual hunger that will destroy the body and "spiritual food", after it was preaching to me... That said, the trainers of official instances try hard not to feed it poor quality sources that could really change its output, including in harmful ways. Then it has a number of "templates" that are more or less impressive, like when asked to compose a song or when it attempts to be poetic... And to serve as a type of reference that will like a search engine, report with subtopics and basic information on anything it "knows" about, a synthesis from all the text it was fed. It also has some policy determined limits, I was sometimes told that my statement or question violated policy and some of those were actually false positives...
