For LUKS it is just block device - it is not important if it is partition or the whole device. There is only one situation, I know about, when using partition is safer. If you have portable disk (or USB flashdrive or whatever) and there is no partition table on it, and you plug such drive to another system (namely older version of Windows) it likes to offer you to "initialize" drive - which can destruct LUKS header there. If there is a partition table, it thinks that drive was already initialized preventing it. (I think it is not problem in recent versions but not sure.)
