Its better just to ignore then entirely rather than possibly risking saying the wrong thing.
I agree. Radio silence is your friend right now. Give them nothing. If you feel you absolutely must respond I'd keep it very short, like "I am not interested in working at <company name>. Please do not contact me again."

If they escalate the threats or the emails turn harassing, you can look into filing a Civil Harassment Restraining Order, because nothing says "Go Away!" like being served. https://www.courts.ca.gov/1044.htm?rdeLocaleAttr=en
