Humans can observe new information, but that's obviously not that unique. We can reason about existing information, creating new hypotheses, but that is arguably a compression of existing information. When we act on them and observe the effects they become information, but that's not us creating the information (and LLMs can both act on the environment and have the effects fed back to their input to observe, so it's not really unique).
There is this whole field of art, but art is constantly going through a mental crisis whether anyone is creating anything new, or if it's all just derivations of what has come before. Same with dreams, which appear "novel" but might just be an artefact of our brain's process that compresses the experiences of the day.
