The 19-year-old was a lively figure throughout the encounter and went close to scoring on several occasions.
Mike Garrity fielded a young team for the clash with the Black Cats in Hetton-le-Hole with 17-year-old Rhian Brewster and U18s captain Conor Masterson handed another opportunity at U23 level.
The young Reds made a bright start to the game with Ojo carrying a real threat down the right-flank and the pace of Brewster causing the Sunderland defence plenty of problems.
Liverpool had an early opening from a set-piece when Paulo Alves picked out Conor Masterson from a corner, but the Irish defender glanced the header just wide.
