So this is what we've come to find out, thanks to further research in the Discord server: Eisente doesn't spawn until those 75 seconds have elapsed. Destroying the initial two Tomcats, one EA-6B, and two Foxhounds can indeed spawn Eisente.

Interesting conundrum, though, is that the Perfect Guide also says on the mission detail page for 14C that Eisente can be spawned if you shoot down all five EA-6Bs in 75 seconds or less from the start of the mission. I'm not even sure if that's possible, a lot of time is spent getting to the first EA-6B. But we know for a fact that shooting down the initial Tomcats, EA-6B, and Foxhounds will spawn Eisente.
