Apple has no more ability to trace an erased phone, or one with GPS turned off than you do. Apple are not a law enforcement agency and do not keep records of who owns what devices and where they are. Privacy laws prevent that sort of activity.
Other phone manufacturers do not track stolen phones either, but just like Apple, some provide services which can assist you in locating a lost device. However technical limitations prevent these services from being guaranteed to find a stolen device.
