If I get sued for whatever reason, are my retirement accounts at risk?
Most retirement accounts are shielded from creditors. The protections are greater for qualified plans, and are lesser for IRA's - so the specific answer varies depending upon how your retirement accounts are structured.

If so, is there any insurance to protect me against that?
Liability insurance for... whatever risk you believe you may have for being sued. Car insurance for your car. Homeowner's insurance for your house. Business insurance for your business. Malpractice insurance if you are a professional. Etc.

With a broad umbrella policy "just in case".
