In short, LLMs are pretty great at working at a single level of abstraction at a time.

You can go from the highest level and all the way down to the lowest level with LLMs, you just have to work at it iteratively one level at a time.

I'm not necessarily suggesting always getting down to literally the function level, although I think that gives you excellent quality control, but having a code-level understanding is clearly an important factor.
