The avatar appearance and content creation parts of the policy are coherent and makes sense, the child safety commitment part however is not. It is out of place and is conflating ageplay with things of real legal significance (like human trafficking) and other stuff that have nothing to do with ageplay or even child safety for that matter, this is inappropriate and should be revisited and maybe separated into its own category or made part of a more serious real life legal stuff category the same way you handle other legal issues.
It also does nothing for child safety when people's attention and resources are tied up by micromanaging what 2 grown consenting adults say to each other while wearing this or that avatar. It should not be of LL's concern as long as: 1. No ageplay is being done, 2. No laws are being broken or 3. No actual minors being involved. Otherwise this overreach creates an atmosphere of unease within community about who reports you for what and how the person reviewing the report may interpret it.
