One way AI can help here is identifying prior art. Write a quick sketch of you idea, and ask an LLM with uncapped long-running web search capability to find if any prior art exists!
The added value of the LLM here is probably zero. Just type a search propmt in a search engine. If the top 5 results don't cover the same ground your article is covering, at the very least, your article will expose new knowledge to people using that search term.
Typing up LLM instructions and reading the output is probably more work.
