I've personally handled 4 ligne 1 lighters and all of them had the automatic shutoff, although it was somewhat busted on one of them, only shutting off if you hold down the flint chamber release button, likely just from wear / age, but that lighter otherwise functions fine so it wasn't worth it to repair it.
