Microsoft Look Book template deployment

LisaJo48 Sounds like when you or another tenant admin used the Lookbook previously, you consented the application "on behalf of the organization". What this means is essentially a Tenant Admin has approved this application for use and the permissions required by this application. I have attached the image of the check box you checked.

I do not think you meant to click this checkbox. When you provision using a tenant admin account, you do not need to select this box. As a result, the other users in your environment can now provision through the lookbook because you provided the consent. 

What you will need to do is....

1. Go to the Azure Portal to your Azure Active Directory settings
2. Go to Enterprise Applications
3. Locate SharePointPnP.ProvisioningApp.Tenant
4. Select Properties on the left
5. Delete this application

The next time you or a tenant admin use the Lookbook, do not consent on-behalf of your organization.
