Not just no, but fuck no.
Intimacy does not scale. No single entity can intimately care about even hundreds of people. So these chatbots are the property of an entity that does not care about you. This is different from people you would interact with in person. A therapist can form a bond with you. Can protect your privacy. These chatbots, by their nature, share with their owners. Who is not you.

If that's your problem then you should be totally fine with a self-hosted model.
There are many people who nobody cares about in real life either.
Just to poke, is a decent AI better than a bad therapist? A bad therapist will absolutely wreck someone's life.
