Clear app cache and storage.
Stop the app process.
Go to the app permissions page.
Turn off all permissions listed on the permissions page.
Go back to the app info page.
Disable Google app.
Go to Settings → Security & Location → Advanced → Device admin apps
Turn off Find My Device
Select 'Deactivate this device admin app'
Go to Settings → Apps & Notifications → see all apps → Google Play services info page
Go to the app storage page.
Clear app cache and storage.
(This app process can not be killed)
Go to the app permissions page.
Turn off all permissions listed on the permissions page.
Go to the app notifications page.

Reboot the phone. Google Play services will complain that it is blind and deaf.
Go to Settings → Apps & Notifications → see all apps → Action Services info page
Go to the Notifications page.
Turn off 'Google Play Services availability' notifications.
Reboot the phone again. Call your voice mail. Google Play services will complain that it is blind and deaf, again.
Go to Settings → Apps & Notifications → see all apps → Phone info page
Go to the Notifications page.
Turn off 'Google Play Services availability' notifications.
(This will need to be done for every app that shows the 'Google Play services error'; The notification option itself does not appear in the settings until after the error is triggered for the first time, for each effected app)
Reboot the phone, again. Google Assistant and Google Play Services are disabled and no longer have permissions to collect your data. Be advised that apps that make use of Google Play services may no longer function correctly.
