I am certain that LLMs can help you with judgment calls as well. I spent the last month tinkering with spec-driven development of a new Web app and I must say, the LLM was very helpful in identifying design issues in my requirements document and actively suggested sensible improvements. I did not agree to all of them, but the conversation around high-level technical design decisions was very interesting and fruitful (e.g. cache use, architectural patterns, trade-offs between speed and higher level of abstraction).
