there isn’t a simple JQL for this but here are you options to consider:
If you use the epic name of the epic in the following JQL - “epic link” = epic-name. If you get no results then epic has no children. Yes not useful when hundreds of epics.
create a scrum board covering all projects you are interested. Look at Backlog epic panel and inspect for Eli’s without issues. Toss the board when no longer needed
look to marketplace for app
