I might recommend rather than counting on finding an appropriate Rando here that you may look into already existing places that might be safe for kids to play with other kids created by adults. I don’t know anything about it but just doing a quick random search online I see some promising things such as this: <a href="https://www.youngdragonslayers.com/" rel="nofollow">https://www.youngdragonslayers.com/</a> and there’s probably more like that. If they’re legit little organizations, there should be some kind of reviews or vetting process that you can feel comfortable with. Also, the official dungeons and dragons discord has a couple hundred thousand people as members so you might be able to find something appropriate there. Here you sometimes see games for kids, but it’s kind of rare in my experience. Certainly do an expanded search if you have not already.
