Very simply, if you don't see a pedestrian approaching from the side due to the limited visibility of the vehicle, then as a driver you have less time to react and slow down. The slower a vehicle is going at the point of collision, the more likely a pedestrian is to survive.
If a vehicle is going 45mph and hits a pedestrian, it doesn't much matter the aerodynamics of the vehicle or even the weight or size of the vehicle, that is an incredible force of impact.
So of course visibility is a factor in deaths and that's why newer SUVs and trucks with collision avoidance systems reduce deaths by 27%.
From [1], "SUVs, pickups, vans and minivans are substantially more likely than cars to hit pedestrians when making turns, suggesting that these larger vehicles may not afford drivers as clear a view of people crossing the road, a new study from the Insurance Institute for Highway Safety shows". Notably, these types of collisions would not result in a roll over the top of the vehicle in any case as the pedestrians are being struck by the corner of the vehicle at an angle.
"Earlier studies have shown that A-pillars — the struts connecting the roof to the vehicle’s body on either side of the windshield — can create blind spots that can make it difficult for drivers to see pedestrians and that these blind spots grow larger as A-pillars become wider."
