Tumble Lubing works even with non-Tumble Lube designs. 

I have a good bit of experience with Tumble Lubing bullets, but not with the Tumble Lube design bullets.  Lee's molds in general are about where they are supposed to be in terms of diameter.  If they are not, sizing might be necessary.  With some calibers such as 9mm Luger, my groove diameters are a bit bigger than standard, so I don't mind a bullet a bit bigger than it is supposed to be.

Errors in how one closes the mold, or failure to keep the mold faces clean of splatter may cause the mold blocks not to completely close, resulting in big bullets. 

There are people who talk about addressing bullet diameter after loaded into the cartridge case, by means of a Lee Factory Crimp Die.  I am not one of those people, but I don't see why it should not work.
