I think you really mean snap-tie cones when you mentioned "tie rod holes." But, whatever--unless you're sure the holes are actually leaking, why bother doing anything to them? If dry and buried behind your finished walls, who cares? Sounds like you might enjoy making unnecessary work for yourself.
On the other hand, if they are indeed leaking, you might consider popping out the plastic cones, if present, and filling all of the holes with a moisture-expanding caulk. I don't recall a brand name for the stuff, but it's supposed to be great for sealing voids--it swells up when wet, making things fairly water proof. And probably pricey, too. Google is your friend.
