For the time being, .local is not delegated from the root. So just not using your ISP's resolvers will do what you want -- recurse directly to the Internet.

There is no way to create an empty .local zone that won't have even an SOA record. I'm not sure if you could do this via RPZ -- probably -- but why bother when you could just remove your ISP's servers from the equation?
