The one thing that strikes me as LLMesque is the occasional use of random and seemingly inappropriate symbols. For instance the lightning bolt and then the arrow/square by the order ahead label by the start an order button. It's also placed in a slightly odd location. The symbols at the top are also kind of weird. I think it's the LLM trying to allude to the cyberpunk theme, but it does a poor job of it in a way that even a low skill human probably wouldn't - because you just wouldn't think to put a part of a rectangle up there beside a checkerboard pyramid thing.

And that contrasts to an extreme degree against the rest of the scene which flows extremely well, maintains perfectly color coordination, and so on. I think it's kind of like how self driving cars can drive phenomenally well but then have occasional failure modes like randomly driving head first into a concrete divider. It's not like that's bad driving in the sense of missing a nuance, but something that's just completely conspicuously outside the rest of its demonstrated abilities.

Yeah polish + consistency but also with busy-ness is a hallmark from what I've seen. It can be tamed, but takes effort.

That said, the provided examples definitely are a clear step up from the "default" you'd get. Like how some bootstrap-templated sites did it much better than others, while the best made it nearly invisible.
