Can a stuck thermostat cause fan not to work?
If the thermostat is stuck open (allowing coolant to flow) it can cause the engine to run cooler than normal so obviously the fan wouldn’t come on…..but not like the engine/coolant can be running too hot and the thermostat somehow effects the sensor reading or operation of the fan.

Why does my Toyota Sienna have low PSI?
Although your psi appears to be low on the front bank and varying greatly from front to back bank I don’t really feel that its a bent valve issue causing them to be low. Normally with bent valves you will see some with 0 psi per cyl. In my opinion your engine should still start with the psi numbers you posted.
What should the compression ratio be on a Toyota Sienna?
Your compression ratio is 10.8:1 on that model engine. Your proper psi operating range should be 162 psi to 216 psi per cyl. Would like to see your psi to be within 5 to 10 psi of each other and on the top side of the operating range.
