There are multiple geo-ip databases. MaxMind's apparently does give an "accuracy radius" https://www.maxmind.com/en/geoip-demo https://www.maxmind.com/en/geoip-demo but many others don't, and of course tools built on top of any particular geo-ip database might not present that information to users.
