There is a funny science fiction story about this. Asimov's "All the Troubles of the World" (1958) is about a chat bot called MultiVac that runs human society and has some similarities to LLMs (but also has long term memory and can predict nearly everything about human society). It does a lot to order society and help people, though there is a pre-crime element to it that is... somewhat disturbing.

SPOILERS: The twist in the story is that people tell it so much distressing information that it tries to kill itself.
