At this point you've created an entirely new copy in an audio/visual digital format and took the steps to make it available to the masses. This would almost certainly cross the line into violating copyright laws.

> Could do the exact same thing with an LLM. The potential for distribution exists in both cases. Why is one illegal and the other not?

To my knowledge, the legality of LLMs are still being tested in the courts, like in the NYT vs Microsoft/OpenAI lawsuit. But your video copy and distribution on YouTube would be much more similar to how LLMs are being used than your initial example of reading and memorizing HP just by yourself.
