Removing Old Gmail Accounts when "signing in with Google"

Hey all, I've searched all over for the answer to this. But in many apps from back in the day before there was the "sign in with Apple ID" option, I used the "sign in with Google" option. I just got a new phone, so I was signing into a ton of new apps, and I have emails that aren't even active on Google anymore as they are with past jobs still in the options there. They are only listed on my phone. Nowhere else are they connected through Google, does anyone know how to remove these? Even if I try to sign in through an App or website on Chrome, they aren't listed there. If I try and sign in through Safari on my phone, they are listed, but when I go to Google accounts in Safari, they aren't listed. The only place they are listed is on Safari on my iPhone when I try to sign into one, but I don't see a delete option anywhere. Not even Safari on my Mac.
