How to remove disabled Google account from Macbook?
One simple means would be to make a new user account on the Mac. 

You can verify the undesired account isn't in the systems preferences and then start using the google services you wish. 

If the accounts are still tied together, you know it's coming from google and the servers in the "cloud" and not your settings. 

If everything is good on the new account, then start going app by app and removing saved passwords, saved accounts, cookies and session caches until you clear up all the automation you have accumulated for the old and now undesired account. 

App by app might start with: Safari, Keychain, Chrome, System Preferences (accounts)
