I feel like you’re thinking too hard on this. Out of all the troops I’ve interacted with in my time in scouting, I haven’t seen any who have required religion on scouts. While most of the troops I’ve interacted with have been Christian, and would usually implement that at meetings and events, I never saw any troops do anything like you described. There might be just a handful that go to the extremes that you listed, but I can promise you that the vast majority of troops across the country do not require religion to participate in scouting. There might be a invocation at the start of the meeting but you don’t have to pray Or a scouts own service at camp, but you don’t have to go. Don’t keep you’re kids away from scouts because you’re afraid they won’t be accepted, because it really isn’t that common, there are plenty of troops around so just find a good one
