Sorry, I just realised they include the pro micro as well! :~Thanks!
The pro micro is not the same size as the pro mini. They are two different boards, which among other things use different processors. The micro is a 32u4 board, while the mini is a 328p. Also the mini is a little shorter than the micro.
The pro mini (if you ignore A4,A5,A6,A7) has a footprint exactly like a 24-pin wide (0.6") dip, with all pins on a standard (0.1") pin spacing, even the interior A4-A7 pins. So it is about as easy as it gets in terms of creating a library part for it. If you are getting into making your own pcb's you might as well bite the bullet and learn to make your own library of parts. It will be nescessary at some point. Further, if you are going to go to the expense of getting the boards manufactured, you are better off relying on your own work then trusting some third party to have done it right.
I can't begin to tell you how many times I have had problems with part footprints with even the software companies libraries. Even if the library is correct for a certain type of part, it may not be correct for the particular package type you end up using...
