Question I'm asking myself is, what's the likelihood there would have ever been fossil fuel deposits with the potential to kickstart a civilization?

#32That’s enough time for a civilization to have been born, lived, and died. Unfortunately there’s probably no way to find evidence of their existence by now it seems? Some day they may say Earth could have been habitable for billions of years.
If there was a civilization on Venus anything like our current civilization on Earth, I expect there would still be evidence of it, even in that hostile environment. If nothing else, there'd probably be unnatural formations of ground from mines or freeway construction or whatever.

Would cooling it help to reduce the amount of pressure the atmosphere has? Isn't the pressure on the surface something like 95 times that of earth.
PV=nRT, so yes, reducing the temperature would reduce the atmospheric pressure. Edit: wasn't thinking at all about the volume

It turns over very fast in geological time

Only half joking by the way.

Surely it would cool below the point where Co2 becomes solid (most of the atmosphere is Co2). Imagine walking around on fields of Co2 :)
