The Google IAB dialog has the Google account name that will be associated with the purchase. In-app purchases are generally understood to be tied to your Google account and apps you download/purchase are associated with the account used in Google play. You could force your users to create user accounts with your service if you want to avoid this kind of Google associated purchasing altogether, but you are going to have a bit more friction for new users. You can just auto generate accounts for your app and associate purchases with said auto generated account, that way purchases are unique to a device rather than something that a user can take with them to a new device. Other than that, those are the only real options. If you need more explicit guaruntees of user behavior, force them to make accounts. If you don't need that, it is OK to use the current Google account.
