No. the truth is, that at this point part of Jill is still believe that thing what Tybalt said where true , especially, because of the photo she saw of MC in his mask, accusing him of stole her panties .
When Trent respond with answer that didn't support Tybalt, that is when she start to realize and continue the conversation, wihc lead to the confrontation wiht Tyblat, and finally Jill see the full picture about Tyblat like everyone else.
This is Why she actually apologize to MC and admit, He was Right all along.
There is no mastermind Investigator Jill

, it was all an accident, she just had an accidental opportunity to talk with Trent.
If this was Jill from Season 1, She would have already Talked with him, just like she went behind MC's back and talk with the school board. But in episode 6, her character shifted, and up until this point she was still believing some of Tybalt's lies.
and this is exactly what and how it happened, and how it is in the Game, written by DPC.
