Most of spying comes on behalf od google framework, that comes with google play. LineageOS wont solve that (actually they refused changes that would allow replacing google framework with microg) but a fork of it will. They are reimplementing oss, google compatible framework, also your battery will last ~30% longer (no battery drain due to google spying).

To use google play store, find yalp explorer.

Why google framework is a problem and why bother with microg? Android developers are using calls to it and without it, half or even more apps would break. Microg implements those calls and fakes electronic signatures of google binaries to keep them working.
