I don't have the Youtube app—or any other Google app—installed (iPhone 12 Pro) but Screen Time showing as 11 hours watched yesterday and more than 9 hours on a different day last week. I didn't watch anything on Youtube (web) yesterday, either (and certainly not for 11+ hours), so I don't think it's getting confused with a web app.
Any idea why this would be showing up?
