What about:

1. "Here is my answer to a comment. Give me the strongest argument against it."

2. "I think xyz. What are some arguments for and against that I may not have thought of."

3. "Is it defensible for me to say that xyz happened because of abc?"

All of these would help me to think through an issue. Is there a difference between asking a friend the above vs. an LLM? Do we care about provenance or do we care about quality?

The difference is in the journey to find the answer, rather than outsourcing it to man or machine. Spending more time reflecting before first post will often answer the easy questions so you can formulate more thoughtful questions.
