I'm not aware of any functionality in the PayPal Add-On that adds a wrapper class to a form when a PayPal Feed exists for that form, subscription or otherwise.
I would check to make sure you haven't added this "product_wrapper" class as a custom class to the form in it's Form Settings. It sounds like that is what is going on.
If you want to style your payment forms differently from your non-payment forms, you can add a custom class to the form itself. You do this by editing the form, selecting Form Settings and then select the Advanced tab. An option will exist to apply a custom class to the form. This custom class will be applied to the main form wrapper.
See this screenshot:
You can do this to apply custom styles to a form. Create the styles using that class as well as css inheritance, and then apply that class to the forms you want to apply those styles to.
