I am not sure what you are asking for. You don't want the author of the form to be able to read the any of the submitted data?
Alternatively, is there a bot or stored procedure that can be set to delete answers so it doesn't have to be done manually?
Sorry we do not support this feature. The author of the form has full access to the data. Any one with access to the form (author, co-authors, collaborators and readers) always have access to the data.
You can only delete the data manually. You can select multiple rows at a time and then delete but it is still a manual process.
