Go to "Settings > General > iPhone Storage".
On the list of apps you will see "Google LLC". This is where Google stores account data and this is shared with all Google apps.
Under Google LLC it says "Data shared by X apps".

However, still i see no "Google LLC" in "Settings > General > iPhone Storage".
(i do see Youtube and Google Home. But after deleting them and reinstalling Youtube i am automatically logged in again.)
I just noticed something else though: when i drag down from the home screen and enter "google" in the search bar, the result list displays a "Settings" item named "Google Home" with the gray ios-settings icon next to it. If i click it to open it, the settings app opens but it doesn't show me anything specific, just the main setting screen.
Note that Google Home is not installed on any of my devices (i removed them a long time ago after ditching the Chromecast).
