A developer develops.

I think "develops" is a decent verb for the activity and it doesn't imply any particular development method.

Technically, I contextualized. But I'd rather use I projected!

"Verbing weirds language", to quote the old C&H comic, but if "to Google" is now a legitimate verb, there's no reason "to LLM" can't become a legitimate verb. "Dilbert LLMed the new landing page yesterday afternoon and the PR is already up."
