You can avoid Google pretty successfully. There are de-googled android or Linux phones out there (or Apple), other search engines, browsers that aren't chrome based like Firefox, a million LLM companies to choose from, service providers depending on the area etc. and you can avoid most of the ads and trackers with a couple of browser extensions.
The one you basically can't avoid no matter what you do is Amazon because basically everything runs on AWS.
Amazon's cloud infrastructure is often overlooked but it's responsible for handling most of the traffic on the internet that's not from China and even there they have subsidiaries that conform with regulations.
