Here is the Kleptomancy rune description :

PASSIVE: After using an ability, your next basic attack within 10 seconds has 25 Range icon bonus range. If the attack is against a champion, you gain Gold 5 Gold. Occasionally, you will gain a consumable item instead. If you gain a consumable item while your inventory is full, the consumable will instead be consumed.

What are the exact odds to receive the consumable? Does it change during the game?

    There was nothing revealed by developers. It's possible to calculate after thousands of matches, but would ultimately never be 100% confirmed. There is anecdotal evidence that it prioritizes items that benefit you (eg: grant you magic elixirs more often than AD ones if you're AP)

There's a post on reddit regarding this. Though it is just an assumption, TS has done great work on calculating all the chances. From what I can see, the chances do scale up.

According to the graphs and tables presented in that discussion we can track that that overall proc rate increases from ~30% at the game start to the max of ~45% proc chance in a game that lasted for more than 52 mins. That is linear proc chance we can see in the graph. We can still observe spikes up to 70% in the mid to late game and down to less than 20% in the early to mid game.

Here I will cite the author: Looking at the data points, there are a couple things we can assume: - The chance of Kleptomancy activating scales up with game time. - Getting sustain potions scales down with game time. - Getting combat potions, Control Wards, and Farsight Wards scales up with game time. - Getting Minion Dematerializers, Sight Wards, and Potion of Rouges appear to stay relatively the same over the course of the game.
