I asked on Mastodon but no one seems to know so I thought I’d ask here as well.
I’m looking for an app that provides the same or similar functionality to Life360 but instead of using Google/Apple map data it uses OpenStreetMap data. Does this even exist?

I’ve never used it, but there’s a location sharing plugin for OsmAnd that shares location via Telegram:
https://osmand.net/docs/user/plugins/osmand-tracker/
Unlike Osmand itself, the Osmand Tracker app is not open-source. While that’s not a quality the OP asked for, I think it is important to note in this context.
Also, I found that Osmand Tracker drains your battery like crazy, but ymmv.
