I think having access to computer analysis would allow the advisors (both honest and malicious) to provide analysis far better than their normal level of play, and allow the malicious advisors in particular to set very deep traps. The honest advisor, on the other hand, could use the computer analysis to find convincing refutations of any traps the dishonest advisors are likely to set, so I am not sure whether the task of the malicious side becomes harder or easier in that setup. I don’t think reporting reasoning is much of a problem here, as a centaur (a chess player consulting an engine) can most certainly give reasons for their moves (even though sometimes they won’t understand their own advice and be wrong about why their suggested move is good).
It does make the setup more akin to working with a superintelligence than working with an AGI, though, as the gulf between engine analysis and the analysis that most/all humans can do unassisted is vast.
The problem is that while the human can give some rationalizations as to “ah, this is probably why the computer says it’s the best move,” it’s not the original reasoning that generated those moves as the best option, because that took place inside the engine. Some of the time, looking ahead with computer analysis is enough to reproduce the original reasoning—particularly when it comes to tactics—but sometimes they would just have to guess.
