Thousands pledged to do mitzvahs in Liora's name and raised more than £20,000 for the Hatzola ambulance service on a special JustGiving page.
Liora's parents, who are members of Hendon United Synagogue, had maintained a bedside vigil as she lay ill at the Royal London Hospital.
On Friday and Saturday, shul goers in Hendon were given updates by Rabbi Mordechai Ginsbury, who led special prayer services. The community said tehillim together to pray for Liora's recovery.
A family friend said a religiously observant senior lawyer had been assisting the family as Liora's parents fought to have her medical treatment continue.
A series of meetings had taken place last week as the family pleaded with doctors not to take the teaching assistant off life support.
It is understood a court hearing took place on Friday to discuss how long her treatment should continue.
The friend said the level of halachic oversight in Liora's case had been "unprecedented" in this country.
