I was going through car rental agency SIXT's ToS to understand whether they provide any liability insurance coverage if one doesn't add one of their protection options when renting a car. I read in their ToS:
SIXT does not extend any of its motor vehicle financial responsibility and SIXT does not provide any liability insurance coverage to renter, passengers, or third parties through this reservation unless SIXT is obligated to do so due to legal requirements or according to the rental agreement.
Must car rental agencies provide the state minimum liability insurance or ensure that the customer has it when renting a car in the USA?
If state-specific, I'm mostly interested in California and Washington state, but I am curious about other states too.
I have read vague statements about it:
https://www.nerdwallet.com/article/insurance/rental-car-insurance:
rental agencies typically have minimal coverage on their vehicles.
Typically means not always.
https://www.iii.org/article/rental-car-insurance:
Liability Insurance – By law, rental companies must provide the state required minimum amount of liability insurance coverage—often this does not provide enough protection. If you carry your own auto insurance and have opted for higher liability limits (which is recommended), you’ll be adequately covered. Non car-owners who are frequent renters have the option of purchasing a non-owner liability policy, which can provide the additional liability needed.
I don't know if that applies to any US state.

Supplemental liability coverage is available, but the car rental may include state-required minimum liability insurance
"may" is not the same as "must.

The following chart lists the Automobile Financial Responsibility Limits of the various states. Hertz is not required to provide such minimum protection in all states.
Hertz clearly says it depends on the state but it doesn't say in which states car rental agencies must provide the state minimum liability insurance.
