Sure. In many jurisdictions, all that is required is proof of financial responsibility. Insurance is only one way to provide that proof.
If you can post a bond for whatever your state's minimum level of financial responsibility is (between $25,000 and $75,000 in most jurisdictions), you'll be self-insured.
Shop for insurance companies that specialize in teen drivers. Compare their rates to adding the teen onto the parents insurance. Often adding the teen to existing insurance is the less expensive way to go.

the episode "nevermore"
It is usually not necessary to insurance a driver who only has a permit. Often, if it is a young person, they are covered under their parents insurance. If it is an adult, then they may insure the driver.
No insurance company has particularly good rates for teenage drivers. A teenage driver costs about three times more to insure than an adult. Always shop around several insurance companies and see how low you can haggle.
As long as you pay the insurance premiums, there is no limit to the number of cars one driver can insure. The insurance companies will be happy to do business with you.
Cost of insurance policies for young drivers depends on where you purchase your car insurance. Adding a teenage driver to your policy will probably make your premiums go up, but teen drivers are to be insured regardless. You will have to call around to see what is reasonable at several insurance companies to insure teen drivers and get the best quote.
