The AI tires are constantly with the exact same temperature (ints and wets 65, slicks 90). The scenario shown in the pictures is during a wet race when the rain was clearing and the track was dry. It...

Your right, AI had tire temps prior to 2018, but 2018 was when they separated it into surface and carcass temperatures which is what started causing problems so they disabled it for the AI. Now whether this limitation is a result of the game engine or the devs coding ability is a fair question, but it's not exactly a bug that's capable of being hotfixed in a patch.
I just identified that there is tire temp simulation for AI for the Gran Prix mode but not for Single Career nor 2P Career.
What makes you think so? There is no proper tyre temp simulation in the game, scripted heating of tyre temps after leaving the pits and thats it for the past few games and not different with this one from my testing.. So im very curious to know what you saw that makes you think there is proper simulation in GP mode
