Honestly none of the companies are tuning their model to be better at therapy.
Also it is not expected that the training material for the model deals with the actual practical aspects of therapy, only some of the theoretical aspects are probably in that material

BrickLabs have developed an expert-fine-tuned model specifically to provide psychotherapy. Their model has shown modestly positive results in a reasonably large preregistered RCT.
The leading edge models are trainable via instructions. That's why agents are possible. Many online therapy or therapy companies are training or instructing their agents in this domain.
That still wouldn't allow for edge/unusual cases and situations which I would say having experienced group therapy for many years, most significant therapy users have quite a few of.
