Will car insurance pay for a car totaled in a DUI accident?

It should. If the "At Fault" vehicle is insured, it's supposed to cover the victim's vehicle 100%. If the "at fault" vehicle has comprehensive and collision insurance that insurance is supposed to cover the at fault vehicle up to the deductable amount. Note that the drunk driver will loose his insurance and be required to get the VERY expensive DUI "insurance endorsment" since he/she is now in the highest risk bracket. BTW, when a drunk driver causes a collision it's not called an "accident". Accident is when things just happen. Driving drunk is the CAUSE of the collision and as such the collision is not called an accident. Call it a wreck, crash or just about anything else that takes away the implication of a random act.
