You wouldn't need rim tape, since there are no spoke holes to cover. That being said, seems like there have been some bad experiences with tubeless tires on non-tubeless rims (though I ran the original Hutchinson tubeless on some 2003 Ksyrium wheels [which also have no spoke holes in the rim bed] for a couple of years without issue).
If you just want the flat protection, get tubes with removable cores and add sealant. Same level of puncture protection, but pinch flats are still possible if you run too low a pressure (but that's more in your control than the errant nail or glass shard).
