I really doubt you have blocked all Google domains. They own tens of thousands, probably much more.
Also, Google provides public services by hosting assets such as Javascript libraries - are you blocking those as well?
If you don't want Google to track you you should just not visit Google domains, block Google analytics (and other trackers) and inspect your cookie cache every now and again to see what's leaking. That should suffice for a non-obsessive level of Google paranoia.
