JetBrains supports TODOs in every language I use/am aware of.

Your syntax assertion doesn't make sense. Commented code is supported without interference in every common language I'm aware of.

You can configure JetBrains to treat that character the same as a TODO.

(Not sure why I'm replying to what is probably AI-generated nonsense rambling, but hope that's helpful in case you're being earnest.)
