I don't imagine Kate to be super gifted with computers besides idk... whatever Bat levels of hacking/encrypting are (and even those vary among the Batfam), but with proper instructions she might be able to prevent small surges depending.

Since they have Jaime/Beetle on the team, she can lend muscle. She weaponized herself a year ago, which means she's got some super strength kicks and jabs going on if they encounter any physical resistance. She's not here to hurt anyone provided they aren't trying to break/maim/kill anyone on the team, or she's not afraid to dislocate a wrist or ankle for further prevention.
