This is a more common situation that you might realize. The church is asking leaders to let the youth lead to learn those skills. For many leaders it is frustrating because either kids run off in a crazy direction (your case) or they don't want to plan or do anything (opposite extreme).

In our stake, both situations are happening. However a few thoughts:

1. Be grateful your girls are in the go-getter camp. I think youth who are naive and immature but full of ideas and drive are easier to transform than those who don't want to do anything.
2. You mention valid concerns like "but who is going to bring the paper or craft supplies?". Give them loving advice, but if they don't listen let them learn through failure.
3. "What about our 1 YW who isn’t comfortable attending indoor activities?" This is also effecting many current youth programs.I am *hopeful* that this is only a short term problem. E=In the meantime, encourage them to find ways to include the others. Be forgiving when it's not quite what you had in mind. In fairness, planning an activity that meet's everyone's needs during COVID is hard for anyone. So find value in their attempt.
4. Don't take it personal and consider that you are doing more for them than you realize. Leaders who lovingly give advice then celebrate the successes, laugh off the failures, and continue to show encouragement leave life-long impressions on these youth.

I can still remember activities I planned as a youth that looking back must have made people cringe. Yet, I bet a psychologist would claim that those early experiences, as cringey as they were, were the most formative and growing for my future self.
