She attended Christ the King College.^[2] After completing her GCSEs at 16,^[3] she won a scholarship to train at Laine Theatre Arts in Epsom,^[4] graduating in 2015, aged 18.

O'Connell made her professional stage debut in the international revival of the show 42nd Street in 2016, in Théâtre du Châtelet, Paris,^[5] forming part of the ensemble whilst understudying Peggy Sawyer. In 2017, she moved back to the UK, performing in the same show in Theatre Royal, Drury Lane, forming part of the ensemble whilst understudying Anytime Annie. In 2018 she joined the UK tour cast of Thoroughly Modern Millie, understudying Millie Dillmount.

Her rise to fame stemmed from her role of Anne Boleyn in the original UK tour cast of SIX in 2018. The show's success gave it a permanent home in the West End's Arts Theatre, where she starred in the show until October 2019. Prior to leaving the show, Millie had played the most shows out of every actress in the original West End cast.

Late 2019 brought O'Connell the role of Velcro in Soho Cinders at Charing Cross Theatre.^[6][7] In 2020 she starred in Be More Chill as Chloe Valentine in The Other Palace.^[8][9] She left the show two weeks before its original closing date to rehearse for Hair at the Turbine Theatre, where she portrayed the role of Jeanie. Following this, Millie landed 'her dream role' of Maureen Johnson in Rent. She starred in this revival alongside Six cast alumna Maiya Quansah-Breed, portraying the leading role of Mimi Marquez and Jocasta Almgill, as her partner Joanne. Due to COVID-19, the show only had five live performances before shutting due to government guidelines.^[10] In response to this, the team livestreamed a recorded version of the show during lockdown. They returned to the show in 2021, Millie returning to the role.

In 2021, Millie returned to the role of Chloe Valentine in Be More Chill, showing at the Shaftesbury Theatre,^[11] and then returned to the role of Jeanie in Hair, showing in the London Palladium.
