Suing Texas Department of Insurance?

Emplyees at Texas department of insurance here in Houston take bribes and lie to injured workers about insurance coverage to protect the employer and insurance company handling claim. The laws are being broken & filing a complaint thru the system is basically a waste of time. But I have settled with the insurance company but the attorneys at the office of attorney generals office in Texas filed a motion to dismiss because of the state having eleventh amendment immunity from plaintiff claims and also challenging jurisdiction by federal court. Do I have any options to challenge this?
