That is incorrect. The controller only issues you an approach clearance for the IAP title at the top of the page. Since the localizer is the non precision part of the ILS, you are cleared to fly the localizer portion any time you are "Cleared ILS". THis is true unless the controller has issued any special restrictions. Some pilots make statements like "request the localizer approach..." or "request the ILS localizer procedures". But that is technically not necessary. Either way the controller should then clear you the ILS IAP. Even if the GS is out he is supposed to clear you the ILS and advise that the GS is inop. This is all per the ATC req FAAO 7110.65 Chap 4 Sec 8.
