So, the surface would be insulated with layer upon layer of basalt crust, making a cool underground environment for creatures.
What matters is what is between the surface and what lies below.
Ordinary silica basalts melt at a lot higher temperature than that, and until they do, they make very good insulators. The insulator “rock wool” is made from basalt. Typically, when it is liquid, gases bubble through it while it solidifies, leaving it full of bubbles.
“Venus has no evidence of plate tectonics, so the theory is that the interior of the planet heats up (due to the decay of radioactive elements) until material in the mantle is hot enough to force its way to the surface. The subsequent resurfacing event covers most or all of the planet with lava, until the mantle is cool enough for the process to start over.”
This “resurfacing” would be ideal for silicates like basalt to erupt from the equivalent of a supervolcano, repeatedly covering the surface with layer after layer of insulation.
Thus the area far away from the eruption could be relatively cool, underground.
