In this specific case, it's hard to see how LLMs can get you from here to there. the problem isn't the boilerplate code like when you build a react website with them, but the really novel architectures (and architectural decisions, more importantly) that you need to make along the way. Some of those can seem very arbitrary and require deep understanding to pull off. You can't just use language-like tokens to reason this out. Fundamental understanding of the laws and rules of thumb are important.
