Parental controls on Apple devices already let you set per-app screen time limits. It seems to me you could easily if-gate content loading with a system API call to check that level of content is permitted. This would even make sense for things like Netflix, who could show age-appropriate content based on the setting. There's already an Apple ID setting for appropriate age content in any case. It seems like there's just a need for an API to use it. I don't think it's a liability issue - parents are presumably expected to enable these controls. It isn't the job of the device to try and enforce the child's age, it's the job of the parent to set the "threshold level", and then Apple can simply require apps announce any threshold changes (or query to see the allowed threshold).
