Pihole will show you devices and the domains they access, it's not particularly designed towards that end, but it can. You can sit down with them and have a look at their history? I use Pihole to block nefarious sites (malware etc.) but also I use the OpenDNS (now Cisco) family friendly DNS addresses as nameservers. I can add domains if needed through the Pihole interface, or through the OpenDNS interface (former is easier). It's not watertight, but I figure if they can work out how to workaround it then they're at a level where I should give more generic guidance. They get exposed to porn and what not on social media (which I don't block) and through friends at school and through their friends devices, or connecting to other networks I don't have control over. Easiest workaround imo is to fire up a browser that uses TOR. Mind you we're a computer/consoles only in family rooms household and they don't get phones until they go to highschool (11yo).
