I couldn't find anything via google, novacycles.com, bikelugs.com or at henryjames.com. I can probably make 75 degrees work with 74 degree lugs, but I'd rather not if there's something that's already supposed to be 75 degrees.

There may be some but no need. Take a "74" degree seat lug for example. Put a top tube mitered to 74 degrees in the lug with a seat tube and see what it sits at naturally. Its anyones guess what that lug angle will actually be. It wont be exactly 74 I can tell you that, it might even be 75. The angle they are labled is more of an average, they are not exact at all.
I use 74 degree seat lugs on almost all my builds, and I use that to go anywhere from 71 to 77 degrees, no problem at all, especially a seat lug. You just need to be concious of what parts you grind out, and make sure your miter is exactly 75 degrees.
