LLM comprehension question

Basically, does anyone else also get a really strange sense of lingering confusion and non-comprehension when an LLM explains a complex concept or tries to give a long format dive into something? It's not that they necessarily get it wrong, most often they can communicate the information cleanly and accurately, especially in things like, AI scripted youtube videos where they creator had their finger on the pulse of the informaiton. It's just something about the way it's said and the flow of the actual language itself, that feels like some sort of comprehension uncanny valley.
