I don’t believe any AI has the ability to do what you’re asking. AI often fails at the simplest of programming tasks, and even when the output runs, it usually has some major flaws.
Even if the AI could do what you want, it would take more effort to find the right prompt than to just do the work, and the prompt would be longer than the resulting YAML code.
You can ask for advice on specific home assistant features, or offer to hire someone to build the interface for you.
My personal recommendation is to just give it a try. Make a few interfaces and automations, and try downloading and modifying other publicly accessible interfaces and automations until you’re happy with them. The YAML code makes it easy to copy other people’s work, and the non-YAML UI makes it relatively easy to try things without programming knowledge.
