No, but you'll want one.
Cooking releases a lot of water vapor(good in the winter, bad in the summer), oil, and odors. There nothing like trying to get rid of a smokey oven while having a dinner party.
Unless the kitchen is on the corner of the house with two windows with a warm breeze for cross-ventilation, something is needed.

See above. Look for used vent hoods at Salvation Army, Craigslist, and other resale venues. Hook it up and listen to the motor, clean any buildup off the blades with alcohol or another solvent, and maybe repaint the hood.
You have a downdraft already.
-It may be a recirculation one(which is garbage IMO because warm air rises).
-It may be a vented to the outside. Check the floor underneath to see if there is a pipe running to the exterior rim joist.
If so, this penetration on the exterior will have to be blocked off esthetically, the drywall knocked off the kichen ceiling, and new piping run to the exterior. That may cause a serious structural problem depending on which way the floor joists run. The siding will have to have a hole cut in it, and a flapper vent installed to keep cold air from entering the house.
With my new house, I had a vent already in place. I installed a microwave with a top-vent exhaust and just hooked it up to the existing piping, sealing all connections and joints with metal tape. Two bird with one stone.

One to the outside is better.
Recirculation-types only trap oil.
