No one is saying that AI can consent to a contractual agreement, however all the time we humans consent to a contractual agreement presented to us by some software tool on behalf of a company. That's what's happening here too.
I can sign up for all sorts of services without a human in the loop.
Amazon used automation to offer me a sweetheart deal to not cancel prime (For example). Because it was a computer program that did it, does that mean they don't have to honor it? Of course not.
A simple non-AI program - a web frontend - can consent to contractual agreements; of course, it's just a tool operated by the human employees, but so is the AI chatbot, and the e-contractual agreements offered and accepted through that tool are just as binding no matter how complex that program is.
Not even that - I guarantee that somewhere you'll find a T&C that says that only certain employees or company officers can enter into binding agreements that alter the standard conditions of sale.
This is about amusing, but just you saying "oh by the way this is legally binding on you" doesn't make it so.
(Even moreso if you're all over the internet talking about permanence in AI models...)
