It's possible to use Android as bundled with a Pixel device without a Google account, but it's a hassle because you can't use Play Store. You can use Aurora Store as an anonymous client, F-Droid for open source apps, APKs from download sites, or the like if you're so inclined, but all of those add significant effort or unreliability.
I tried to daily a phone with MicroG for a while and had lots of trouble with location accuracy and speed. I tried out several third-party NLPs but never got acceptable results.
