I've just checked and I can confirm you that the mod that you are looking for is available (gen 2 style sprites only for normal sprites of all generations)
Once you've downloaded the .zip file, go to "private sets", then open the "all mons" folder. Inside you'll find 3 mods, the one you are looking for is "Gen2-all-no-shinies".
I have to point out that that version isn't updated and many animations are missing. We'll make sure to update every mod with every animated sprite we currently have asap. Let us know if you have any feedback.
Enjoy our mod!
