Hi!
I think we are talking about different things 
There was a bug for filtering rooms in admin > rooms.
This is now fixed on latest 4.3.1 already:
Now you can filter and edit rooms, teams, and others.
But I think this will fix your issue.
You can let users create teams, and inspect if they are creating at the Admin > Rooms UI.
Or you can deny them this permission in Admin > Permissions.
Thanks!!
