Flying domestically in the US using a foreign passport as an undocumented person

I’m an undocumented person who’s living in the USA and I’m wondering if anyone out there has any advice or stories on flying domestically using a foreign passport. I’m 33 and have been in the US since I was 4 but still have no status so I don’t sound foreign. I’ve talked to my immigration attorney who’s told me that TSA doesn’t check for immigration status tho there always might be BP or ICE agents who could randomly stop me. Anyone know how likely this is and how to handle that in case it did happen? I’m considering traveling to visit family on the other side of the country and my passport is up to date and I know TSA guidelines state that foreign passports are ok.

Wanted to hear input before I make a decision.

Thanks
