Dealing with an old sink and looking for help.

Q1: I’ve looked for “faucet supply lines” to the specifications on the tag but none of them fit this bottom connector look, has it been modified or do I need a speciality line?

Q2: I’ve seen recommendations for 2 hole faucets for this situation, but with copper tubing I wanted an at least somewhat experienced opinion before I started ordering. What do you recommend for this type sink?
