> I run a local system that mirrors approved channels to our home server and serves them through Plex. Creators lose ad revenue; that’s unfortunate.

Have your home server note when the kids are watching one of your mirrored channels and launch a browser on a computer the kids cannot see that is watching the same video on YouTube without an ad blocker.

The video creators then get exactly the same ad revenue and view counts they would have gotten had the kids used YouTube.
