Is there any legal action I can take, after leaving for a job after boss makes unethical request following unique circumstance? -under the table

I was a nanny, getting paid under the table for, I think it's was just under two years that I was employed. I resigned from the position in mid to late June 2022 after my employer requested that I started to use a password protected application for encrypted texts and calls, following unique circumstance involving my fiance, who unfortunately struggles with c-ptsd. Realizing that my employer was, I'm a sense, asking me to lie/ keep secrets from my fiance, KNOWING he has c-ptsd, strikes me as inappropriate employment conduct. As an under the table employee, do I have any rights rights to lost wages .
