In another comment I wondered whether a general chatbot producing text that was later determined in a courtroom to be "therapy" would be a violation. I can read the bill that way, but IANAL.

That's an interesting question that hasn't been tested yet. I suspect we won't be able to answer the question clearly until something bad happens and people go to court (sadly.) Also IANAL.

But that would be like needing a prescription for chicken soup because of its benefits in fighting the common cold.
