Isn't "creativity" the result of a combination of patterns (usually from different contexts) that casually works? I bet LLMs/agents can do that (we can't know how far that can goes).
For me that creativity is very well expressed by the principle of abduction. With induction, generalise towards rules, or deduction, use rules on data, we have this combination of patterns via different contexts. I think abduction might not be possible via LLMs.
