Will the truth be told to us by her?

When the given sentence is changed to passive voice, then the subject, verb form and object are all changed, in order to retain the meaning of the sentence.

So, the object takes the place of the subject and vice versa and the word 'by' is introduced as now the subject receives the action by the object. The verb form of the sentence is also changed from active form to passive.
