You can check that in game by pressing tab and scrolling over it. This goes for the damage you do from Thunderlord's, the fervor of battle total damage boost (damage per stack)x(max stacks), and I do believe bond of stone shows how much damage you transferred (kinda like how the support items show the different gold gained, which i find their different gold things are a bit weirdly shown).
Assuming that you are meaning in the after game stats window, they try to keep the main stats that the majority is worried about, and stray away from the more minor ones like the various keystones. It would be hard to add those in without it looking fairly cluttered, which they have been trying to avoid it becoming so that it is more manageable.
I also know that it reeaalllyy depends on the game, because if you are only able to hit 3 times to poke most of the time, you will almost always do more damage than with fervor. Fervor requires constant, and rapid, fighting. You may want to stray from the totals of the different keystones because situations vary so much. For example Thunderlord's might do more damage in total, but its for burst and pokes, so if you don't kill it just becomes kinda useless damage. Teemo shrooms are a good example of this, most of the time Teemo shrooms don't kill, but they do a hefty amount of damage over time leading to them having most damage to champions. Teemo could also be 0/40/0 and have most damage to champions that way. Does that mean Teemo carried because they did the most damage to champions at the end? Just keep that in mind when looking at the totals, because some keystones really are better for a champion than others based on kit, but others can fit better in different situations.
Also the games will vary depending on who is on the enemy team, how they play, how you play, what items are built, etc.
I do believe that they do have the keystone stats featured best they can, and that is in the tab in game. Hope that it helps you in case you didn't notice that feature though.
