So, anyone know if the Leitz Wetzlar anlegefalz 9x12 holders will work for a Voigtlander Avus?

It doesn't look so. I understand that you're eager to start using the camera, but relax and check eBay every day and you will soon find original Voigtländer plate holders. I bought around twenty 6,5x9 plate holders for my Voigtländer Bergheil within a few months after getting the camera, and nine 9x12 after I bought my 9x12 Avus (and later also bought another Avus plus a Bergheil 9x12).

They are fine cameras and fun to use.
