I strongly hope there is a first-party solution for this, without having to use Google stuff in my apps and such.
Ummm...No. I believe currently Apple doesn't provide any ad solution inside apps.
To provide ads in your app you can use google's AdMob services. But you don't have to use AdMob, just search 'AdMob alternatives' and you will find other ad providers. Check if the ad provider allows you to set the ads to be child-safe (AdMob does provide this option).
