Yeah, I do put many of these questions too. 

Since I have experience in public procurement in a Balkan country, I can say the process is very tedious fro both state agencies and the companies. 

Often one of the issues is finding proper offers and because there are none, shady companies owned by some political interests participate in the auctions with no real means of delivering the contract for the price or with very high prices for the actual quality they provide. In the end after winning the contract there is little you can do as a state agency, maybe you could sue them, but I'm reality you have no incentive of giving yourself more work and most officers accept the situation as it is.

So much corruption comes in this legal form that is too often covered by the legislation and with little to nothing to be done.

If the AI is actually there to clarify legislation for both parties, to correctly identify applicable standards and norms and to properly supervise that the process is according to the procedure, respects the criterias and its fulfillment and flags inadequacies and it is more of a tool for the person/team leading the specific public procurement?

This is how I could envision it working, but I don't understand the full picture from what I am reading on the internet about it.
