I think you misinterpret the 'don't know how' part. LLM's are fantastic for boilerplate (which is a big part of getting things started). From there, I might not know the right incantation for (say) handling a button click, but it's not too hard to validate that an LLM-generated handler a) works, b) looks sensible, and c) fits reasonably in the codebase. In fact, most of my use of LLMs for coding is about generating snippets of functionality, which go into a codebase that I'm maintaining the shape of... which helps maintainability. You can also generate tests more efficiently, meaning you can get better test coverage cheaper. This leads to better maintainability as well, as you know more quickly when you've broken things with a change.
