Regarding your concerns about tutor emulation, your argument seems to be students use chatbots as a way to cheat rather than as a tutor.
My pushback is its very easy to tell a chatbot to give you hints that lead to the answer and to get deeper understanding by asking follow up questions if that's what you want. Cheating vs putting in work has always been something students have to choose between though and I don't think AI is going to change the amount of students making each choice (or if it does it won't be by a huge percentage). The gap in skills between the groups will grow, but there will still be a group of people that became skilled because they valued education and a group that cheated and didn't learn anything.
