In humans, language is based on the state of the world, and anticipates future states of the world. In an LLM, language is just language.
If an LLM says "my favorite flavor of ice cream is cookie dough", it's just a statistically plausible thing to say.
If I say "my favorite flavor if ice cream is cookie dough", it's because I'm trying to deceive someone, because for some reason I don't want them to know my real favorite flavor is cake batter.
