I'm not a fan of Clearview AI, but I understand it's still useful even for faces that aren't explicitly tied to an identity in the system, because the if the police know where the matched photo is from, they can do the legwork to fill in the missing details.
I think one of the examples in an early article about it had the police feeding a suspect's face into it. The system found a match in the background of some photo taken at a trade show (the guy was working a both). It only knew the website the photo was from, which allowed the police the identify the trade show, which allowed them to track down the people working at that booth to find their suspect.
