How to use safari and not google on 16 pro?

• To learn how to change your iPhone's default web browser please read Change your default apps for features on iPhone and iPad - Apple Support. Safari is the only web browser included with an iPhone, but you can install others.
• To learn how to change your iPhone's default search engine please read Change your default search engine on iPhone - Apple Support. You can choose among several options other than its default (Google).

I suspect there is more to your concern though. Describe what you are encountering in detail because I don't understand the statement "I just know I’m not getting messages that Safari blocked bad traffic on my phone."

Are you asking about Safari's Privacy Report?

Safari Privacy - Apple

That is written for Macs but Safari for iOS does the same thing. I'm not sure what you mean by "switched to Google" or why anyone with an iPhone would intentionally want to do that.

Safari is a web browser, not a search engine.
