Except that the endgame of the PRT is not to put her in jail, but to legally force her to accept doing heroics under the Wards, and in that sense even a judge partial towards Taylor is going to see the logic in the fact that getting training, support and gear is physically safer for her that not getting the perks of the Wards Program, and in a minor physical safety or at least risk management is a higher priority than happiness and independence. So if the PRT gather a list of minor crimes Taylor makes by mistake as an unsanctioned independent hero, the fact that she is already a Ward and therefore has access and opportunity to get that training and the fact that as a ward of the state after she asked to be officially separated from her father (remember, she asked not to see him again under the excuse of not feeling safe under him, a De Facto acceptance of the guardianship of the Protectorate) they do have enough legal and moral authority to forbid her from performing unsupervised heroics the best case scenario of Taylor getting in front of a judge for crimes related to vigilantism is that she gets off with a fine and a suspended sentence, the judge giving the Protectorate orders to officially keep an eye on her even during her YG free time (its a poorly worded administrative measure not a law, so supervising that time after even a minor misdemeanor is well within the authority of a judge from juvenile court) and that if she goes back to vigilantism then she officially enters probation, and even if her sentence is for a misdemeanor instead of a felony is probably enough to overcome her right to deny Power Testing, therefore fully getting into the authority of the Wards.
So yeah, getting her in front of a trial would be a losing proposition to her even if its also a losing proposition to the PRT/Protectorate for different reasons.
No it wouldn't, because the fact of the matter is, probation and suspended sentences, rely on the accused agreeing to them as alternative to the standard punishment, which mean the standard punishment, need to be higher than Taylor find acceptable to go though to avoid the probation, if she's only up for some fines and a few months in Juvie, then Taylor refuse the probation agreement, go to Juvie for a few months, and so the alternative sentences can't be applied to her, meanwhile all the dirt on the PRT has still been unearthed.
The problem is, that for Taylor to agree to extra restrictions in return for a suspended sentence, what is suspended need to be actually bad enough that she consider it a high priority to avoid, a month or 2 in Juvie don't count as bad enough.
If they can only get her for minor things, while it drag their major crimes into the light, then it's a win for her, because she can take the minor punishment her sentence comes with, while the PRT get dealt a major blow from all their crimes coming to light, if Taylor has to go to Juvie for a few months, to get Emma and Sophia sent to jail for years, then that's a bargain Taylor will take.
It's like with the previous runaway discussion, if Taylor become a runaway and get captured, the PRT can find something to charge her with, but they likely can't get her on probation, because the combined charges wont be enough that she would rather go on probation, than take the punishment probation would be an alternative for.
When you hate someone, losing a centiliter of your blood, to bleed them of a liter, is not in fact a loss.
Both the PRT and Taylor having legal consequences happen to them, is only a loss for Taylor, if the cost to herself, is more than she consider worth paying to inflict those legal consequences on the PRT.
