Do you have Google Play Services on your LineageOS device? It's amazing what Google can push via that these days. ;)
As a note, for non-rooted users, it's common for Android vendors to push mandatory updates. Both my last Android phone and tablet before I left the platform were pending 'mandatory' updates where I had to kill a process after booting to prevent them from executing.
