Question

add new user to Search service application will create the user account login under SQL security , due to security team request we need to remove the user account from SQL server .
After remove the user permission from Search service application SQL permission is removed but the account still available at SQL server
try to manually delete the account from the root security but notice that under search database still have the user account there (with no permission) and some schema over there.

my question if we just delete the account without clean up the schema will causing SharePoint patching failed in future ?

I don’t think manually clean up the account (not service account) will cause hidden issues.

Which account are you referring to, specifically? You need to maintain accounts in SQL in order to properly run the service.
