The Tenno did not kill all of the Orokin, they just killed off the high ranking Orokin.

The Guardsman Synthesis entry happens well after the slaughter at the Terminus. In it Alarez is clearly a living Orokin, just not a particularly high ranking one. As well, that entry makes several references to genetic lockouts on Orokin tech.

The Empire fell because the Tenno killed everyone whose genetics would have allowed them to operate the important ifrastructure of the Empire, things like the Towers and the Solar Rails. Well, that and Lotus shoving the entire moon into the Void. Considering it was the government/control center of the Empire.
