That will only take effect when the app happens to be localized in Lithuanian. Apple does not make any like that. They publish the available localizations at

The language (Lithuanian) is chosen as Primary in the Preferred languages list, unfortunately Lithuanian doesn't appear as an option in the list for languages for applications, although I would like to make Lithuanian the automatic language for Pages. Is there a way to make that happen? These are the only languages given as options for Pages application (although I checked other applications, and Lithuanian isn't given as an option for other applications either):
