Stats were kept by Lindenwood for both games, as
@JMCx4 points out Air Force has included the game reports in their recaps. You can also find the full box scores through the ACHA website, their scoreboard section is powered by HockeyTech. You can also access the game reports used by Air Force at these links.

The crew of referees were a crew that works regional NCAA/ACHA, NA3HL/NAHL/NAPHL games. Again as JMC noted, they have worked other LU games before. In addition a MIHOA Board of Directors member responsible for evaluating officials was on site for both games.
Photos from the series were provided to the team by the photographer, and they have been using those in social media content. But I doubt those have been put into the photo database on the backend of the website, photos for the game recaps posted to the LU Athletics site would definitely have been generic ones from earlier home games. Strangely you can catch other NCAA teams doing the same thing (across multiple sports), but to stick with some hockey examples, BGSU obviously used a photo from a game against Michigan for a recap against Miami (OH)
Falcons Battle Redhawks To Friday Night Tie - Bowling Green State University Athletics
Penn State included a photo against LIU for a recap from a game against Canisius. That's a home game too where you'd also expect them to have photos on hand from that game.
Men's Hockey Falls to Canisius, 4-1 - Penn State University Athletics
So the games were played without Atlantic Hockey officials, but Air Force didn't seem to have a problem with that. Stats were kept in real time by Lindenwood. And even larger programs than LU use non game specific photos from time to time.
