Alabama actually doesn't have a large NIL program. Right now they have tons of momentum, tons of history, and tons of Alabama players in the NFL, which are all still important to recruits.
But going forward, it'll be interesting to see how well they can keep up. NIL was always going to be a competitive disadvantage for Alabama which is why you've seen Saban so often in the news, either protesting it directly, or asking for severe curbs and caps on it.
