My husband has started to pee in many places, does anyone know a floor that I can clean and odor-free?

i need something with no grout or joint seams, but looks good in the living room.

There are some linoleum floors that look just like ceramic tile. No joke. No seams. No grout. Start here and Google:

I agree with MaggieMarshal, vinyl is the most practical flooring even though it is not fashionable any more or common living rooms.
In my opinion we need to give up the notion of keeping our homes looking fashionable to if you plan to keep a high needs loved one home with you, the focus needs to be on safety and ease of care. For example scatter rugs have got to go, grab bars and toilet extensions become the norm in the bathroom, clutter and knickknacks need to be removed to make room for walkers, then wheelchairs. If you can't wrap your head around the idea of changing your house into a little nursing home you may soon find that making the even bigger change of having to re locate is the only option.

I was going to suggest sheet vinyl. They make some that looks like tile, but also some that looks like wood. I agree with Cwillie that eventually our houses become more nursing home-like.
