To quote CGP Grey "There isn’t a rule of economics that says better technology makes more, better jobs for horses. It sounds shockingly dumb to even say that out loud, but swap horses for humans and suddenly people think it sounds about right."

I mean I don't know, maybe you're right and this will Jevons us towards even more demand for AI-assisted jobs but I think only to a point where it's still just AI complementing humans at being better and more efficient at their jobs (like LLMs are doing right now) and not outright replacing them.

As per your example, bank tellers are still here because ATMs can only dispense money and change PINs, they can't do their job but only leave the more complex stuff to be handled by less overworked humans since they don't have to do the menial stuff. Make an ATM that does everything (e.g. online banking) and there's literally nothing a bank teller needs to exist for. Most online banks don't even have offices these days. For now classical brick and mortar banks remain, but for how long I'm not sure, probably only until the next crisis when they all fold by not being competitive since they have to pay for all those tellers and real estate rents. And as per Grey's example, cars did not increase demand for horses/humans, they increased demand for cars/AGI.
