I am sure that chatbots will do a "I cannot provide mental health advice" disclaimer and continue doing what they want, but there's probably some very solid reasons in Illinois to do this.

In particular, Illinois has a legal requirement that health insurance must cover mental health services at an equivalent level as physical health services, including care with no end date for chronic conditions. So whether or not a chatbot counts as mental health therapy is likely quite relevant on whether or not Illinoisans can bill insurance for it.
