Also supposing in this situation that AI can’t really perform the job duties. If it can, don’t bother hiring either person.
In this case, you're handicapping the smarter student by depriving them of the AI the dumber student gets.
If the whole point of exams is to test competence, the test becomes totally useless.
One big theme I see is that people want something emotionally out of physics that it just can't give and if you are misaligned on these you are going to accomplish nothing even if you can do the math:

Over dramatized but you get the point. One group is mad about the support the other gets. And that other group loses incentive to really try for things since the solutions, or at least the paths to them, are always sitting there waiting.
If you want your GPA to have a lower AI help associated with it, then you will try harder.
This extends to standardized tests in general. It is often framed around class and race, but I think the real enemy of standardized tests is the "legacy admission" who can't test his or her way out of a paper bag. Ever other element in society is corruptible, people can use their social capital to influence teachers and school administers. Certainly test prep can give people familiarity with the test which helps up to a point but for a certain kind of student the only way to get a good test score is to hire a ringer to take the test for you.
When objective tests are used to assign kids to gifted programs the usual result is an increase in minority and low-income participation because groups that have high social capital are better equipped to manipulate subjective decisions.
The better way to think about this is as having a TA available 24/7, except during testing. This artificial TA should help guide students to gain understanding, rather then simple hints or answer/mistake guiding
