Keep in mind I don’t know the answer, but I could see it just not going off (oh my yogg that is). Almost in the same vein of snake trap not proccing if the hunter has too many minions. Again, I have no idea, but this is my best guess.
the card reads "instead cast a random one of the same cost" not "instead cast a random different one of the same cost", so I could imagine the original spell is also part of the pool of spells oh my yogg can choose from and it just casts a "new" libram of hope when no other 9 cost spells are available
Now that Libran of Hope is the only 9 mana spell in the game, what happens if u play it at full cost vs OMY? (I don't have the card to test it)
Now that is an interesting question.

Probably still casts the spell but with the target being chosen randomly. At least you got your 8/8 divine shield taunt.
I love you Dreadsteed, I will never disenchant you!
