No, the thing is that one of the Prothean relays was on the Citadel. I didn't read anywhere that they removed it so the Alliance could just discover it in the debris (see: Cerberus and the remains of the Collector base if you destroyed it) and, in time, copy it.
I didn't have Jarvik since I won't pay EA for stuff they removed from the game so I didn't know he was a soldier and not a scientist like Morden, but it doesn't matter. It makes perfect sense that Jarvik would play a major role. He may be a soldier but I expect he can read and translate Prothean better than anyone else alive. He doesn't have to know anything about Prothean science, he just has to be able to help the surviving scientists with translation from where ever they find the plans for the relays.
