What do you mean LLMs don't learn? How do you think they became capable of stringing a sentence together?
They don't learn during a deployment, but neither do humans; humans only learn during sleep. The behaviors a human exhibits while "learning" in the moment are just stochastic parrot behaviors based on their immediate context window, if the human doesn't sleep in time the event can slip out of their context window and they don't learn despite having acted as if they do.
You seem to be very naive about human learning in general. What makes the "truth" of school lessons greater than the "truth" of an LLM's curated dataset it is reinforcement learned on? Have you ever seen actual evidence that mitochondria exist, or are you just stochastically parroting your biology teacher?
I also oppose LLMs in almost all applications (live translation being an example of a good application). But please oppose it with arguments based in reality.
