Because human characters act as a relatable touchstone/ a gateway into that universe. They're not really that important in the grand conflict between the two aliens anyway (as Sc1 eventually shows with Kerrigan not actually doing anything to sway things in favour to the Zerg despite being the determinant the Overmind sought), but they just happen to be there and get-in-the-way sometimes. In that regard, the inclusion of Raynor in the later campaigns (whilst arguably "forced/ fake"), is necessary to give the stakes a relatable and Terran perspective because the story is supposed to be about how these three species interact even though the actual narrative has already excluded any importance the Terrans might have had on it already.
