Billy Jo Revie, 16, pleaded guilty to breaking into the pub on December 17 and stealing the items weeks after a helicopter hit the roof, killing 10 people.
The teenager's case called yesterday at Glasgow Sheriff Court and was dealt with by Sheriff Joseph Platt, who was involved in an earlier case with those who previously admitted the same offence.
He told Revie: "I'm not going to impose a custodial sentence. You are aware what you did was disrespectful."
She was handed an 18-month community payback order with the condition that she will be supervised.
The sheriff previously sentenced Jordan Parry, 16, and Darren Melrose, 18, to six months detention after they admitted their crimes.
Charmaine Holmes 17, who also pleaded guilty, was given a community payback order for 18 months with the condition she is supervised.
The court previously heard the group were spotted lurking outside by a man who was at the Clydeside paying his respects to a friend who was killed in the tragedy, on November 29.
He alerted the police and the teenagers were caught red handed on camera forcing their way into the empty pub.
Officers then heard them smashing charity tins off of the pavement and saw piles of coins and bottles of alcohol.
Defence lawyer Ann Ritchie, representing Revie, said her client was friendly with Holmes and they had met Parry and Melrose and followed them to the pub.
Ms Ritchie said Revie was "scared" at the time and knew that it was "disrespectful".
The defence lawyer also said that Revie spent time on remand over Christmas and found it a "frightening experience".
