For a typical car insurance policy, what type of insurance would pay for paint/body damage (est. <$500) to another vehicle?

If I hit another car and cause damage to it, but do not have comprehensive or collision insurance, and only have property damage liability coverage, would this cover damage to another car for less than $500? My policy states the property damage liability only applies to amounts I am legally obligated to pay, but it does not have a deductible, so I am wondering if it would pay anything at all if I’m not sued. Would I have to wait until the other driver’s insurance company sues me or my insurance company? Would they even do that for a $500 claim? I am calling my insurance company tomorrow, but am just curious if anyone has any insights/experience as to if or how my insurance company would reimburse me or pay for this sort of damage. Thanks.
