69% is a byproduct of soybean oil production. most people don't want to eat soy cake. some people already do, but not enough to eat the entire crop. giving that to livestock is a conservation of resources.
a large portion of the land used to raise livestock are grasslands. what portion of feed they are given is also, largely, crop seconds or industrial byproduct. the source for your owid link is largely poore-nemecek, a paper I would trust to tell me the co2e of co2
soy beans are an excellent example: they're not grown for livestock. they are grown for people, and what is fed to livestock is industrial byproduct that would otherwise be waste.

7% is fed directly to livestock. 85% is pressed for oil. the byproduct is the vast majority of what is fed to livestock.
