I think this is a false equivalence, by some extreme margin. Teachers may occasionally have some fact or whatever incorrect, but especially at lower levels it's going to be exceptionally rare, and often based on a logical foundation that is otherwise invalid for some reason, like whether 1 is a prime number or not.
By contrast LLMs constantly get things wrong and once they get something wrong will begin weaving that into everything create entirely fake realities of the sort that is more akin to a schizophrenic than somebody being mistaken on this fact or that.
My own experience from elementary school was that teachers being wrong was shockingly common. There is no subject in which I would trust any of my elementary school teachers more than a state of the art LLM. This was in Norway. I’m guessing you were privileged to grow up in a place with better quality elementary education.
