How can I get flight confirmation/book a flight if I don't have my US passport?

Unless you are booking with a 3rd party agency that charges for every little change, pretty much all airlines allow you to book with nonsense numbers (all 1's) and at a later time update your passport info, or even wait until check in, in-person to do so.

Many people do not have passports when they book flights, or they lose their passport, or their passport expires. They are fully aware that until they check the passport day-of, the information might not be correct or valid.
Hey , can you help?
