No one in the US sponsors civilian ab initio pilot training.
Some regional airlines may pay bonuses or reimburse you for some college/flight training expenses but nobody is going to pay for it up front. They want you to have completed training and accumulated enough flight time to qualify for an R-ATP or ATP before they commit any money.
You'd have to look overseas for sponsored ab initio training, and you'd need local right-to-work, or more likely citizenship.
If you wait long enough, like 5+ years, it might become available in the US if the pilot shortage gets bad enough. But you'd probably be better off economically just paying for it now than waiting for a maybe, because that five years of seniority will be worth a whole lot...
