For GIB, even opening in 3rd seat still asks for 12+TP. GIB would deal hands based on that fact.
You have shown ♣KQx, ♠Axx and ♦Qx and ♥x, and hand like 4 spades + 3 clubs and 5 diamonds and 2 hearts or 3 hearts and 4 diamonds.
Declarers promised 15+HCP, but showed only 7 up to this moment. Should have 8-10HCP more.
If you had 5 diamonds you would have +1 TP with Axx.xx.Qxxxx.KQx
But in that case declarer would be KJ in diamonds which it's not like that after play of 3♦ and Jack did not fall.
So here declarer very likely already has ♥AQJ and you don't have ♦J, but missing TP might mismatch somehow GIB's plan and it went wrong and instead of finesse for -1 jumped with Ace and exits with 10.

A human North would know that a human South didn't have the ♦J when South played the Q on trick 7.

GIB doesn't need to infer that South has the J, it can see that its play of 10 in the trick as dummy has no higher card. Just the broken card play mechanics.

GIB does not place a premium on beating the contract if it can detect a way of maximising undertricks. Similar to it not leading an AK against 6N
