My experience is that LLM too often finds solutions that work, but are way more complex than necessary. It is easiest to recognize and remove such complexity when the code is originally created, because at this time the author should have the best understanding of the problem being solved, but this requires extra time and effort. Once the overly complex code is committed, it is much harder to recognize the complexity is not needed. Readers/maintainers of code usually assume that the existing code solves real world problem, they do not have enough context to recognize that much simpler solution could work as well.
