Generally vegan meats meat-fish-seafood-and-dairy-free when you see it on a generic packaging or restaurant.
Kosher at least in the US usually comes with a symbol and you know the ones that are legit (Orthodox Union is the most common in the US, the (U) symbol Ⓤ)
Vegan can also mean food that doesn't involve the exploitation of animals. That version of veganism means no food that requires insect pollinators.
A cutting-edge vegan discussion is whether lab-grown meant can be vegan. An animal need not have a brain to be an animal. And an animal grown in a vat is still an animal.
Is a human without a brain still a human? There are plenty of people in hospitals with zero brain function, some with virtually no brain matter, that still have full rights as humans.
If a jellyfish not an animal because it doesn't have a brain? A worm? Many vegans choose not to draw lines between different types of animals.
That’s not what I was asking though. If you grew just the organ, how is that an animal? I’m vegetarian for environmental and ethical reasons, if we have a way to create a chicken breast in a lab by assembling proteins, I would definitely eat it.

Legal death is defined as brain death in many (most?) places. I think you mean these people are in a vegetative state, but their brain is still on autopilot so the body doesn't completely shutdown.
Some don't eat anything "involving animals", nothing pollinated by bees, but others go with "not exploiting animals" and are ok with bees so long as it is natural pollination. Such vegans draw a line between natural pollination and the commercial delivery of bee hives to pollinate fields. Those hive often don't survive.
