Bilingsley played in nine games with two receptions for 16 yards as a freshman. He caught 18 passes for 287 yards and three touchdowns as the Crimson Tide won the
2021 College Football Playoff National Championship. Billingsley also led the team with 89 kick return yards. Billingsley was moved down the depth chart prior to the start of the
2021 season. When coach
Nick Saban was asked about it after the team’s first game against
Miami, he said Saban said, “Jahleel and I have talked on several occasions because he's certainly a guy that we want to have success for his own benefit individually, as well as for the team. Sometime when you get a little external encouragement it can be a positive for you.” Billingsley caught a 26-yard touchdown pass in the Crimson Tide's 31-29 win in Week 3 over 11th-ranked
Florida and returned to the starting lineup the following game against
Southern Miss. Billingsley ended the 2021 season with 17 receptions for 256 yards and three touchdowns in 13 games. On January 11, 2022, Billingsley entered the transfer portal after not catching a pass during the CFB Championship for Alabama. Then on January 16, it was announced that Billingsley would be transferring to Texas to play with former Alabama Offensive Coordinator,
Steve Sarkisian. He started his time at Texas with a six-game suspension for "something that happened before his arrival in Texas." He left the team before their 2022 season was over.
