Even if the official permission for account info is named "Contacts", Outliner does not and is not even able to read your contacts. Outliner just can list the Google Accounts on your device so that you are able to choose one for Google Tasks sync.
If you deny this permission, Outliner works normally but you can't use Google Tasks Sync.
