It's actually less because it's Litz and more because for wave winding, silk or rayon or cotton-covered wire is used. Even single-stranded wire can be wave-wound if it's lapped with textile thread.
Enamelled wire, by contrast, sometimes has a very thin over coating of nylon, to help reduce friction so it will go through high-speed winding machines better - exactly the opposite of what is needed for wave winding!
