yes, but at the transistor level .... it has no idea at that level how those transistors are arranged into gates directly

The tools can definitely recognize static logic gates purely from the topology (nothing special in the GDS needed). I don't know that I've tested it for anything more complicated, but as you've pointed out, if the hierarchy is in the GDS it's trivial to recover
I take it back, it's a sky130 .gds the gates are explicitly in there
In fact if you have the sky130 libraries installed (it's where I'm working) you can get a spice netlist out of it in about 10 seconds - really they should have flattened it
