"A minor child who downloads a software application from an app store agrees to contractual terms of service, "
Which a minor cannot, legally, do. Without the parent agreeing to the terms, there's no enforceable contract.
The counterpoint is, of course, the impossibility of verifying anyone's age online without pissing off a lot of people who really shouldn't be on the internet to begin with.
No good answers, or even good questions.
