Are there any concrete blocks designed to provide drainage?
I have a concrete block wall at one side of a concrete
patio and there is enough slope that water accumulates at
the wall. I could get the patio mud-jacked to slope
differently. I could get a concrete saw and cut the patio
for a channel drain... but the easiest solution would be a
wall that incorporates a drain. Does this exist? Thanks.

Rebuilding the wall is easier than cutting a drain channel? You can rent
a gas powered saw. If you want to rebuild the wall, you could pour
concrete about 4" high above the patio with PVC drain pipe set in it
and then use block from there on up. Or just make holes in the existing wall
for drain pipe. Me, I'd rent the saw.

Below FEMA walls have to drain or allow water in, depending on where
it is rising. They typically turn a block sideways so the holes are in
and out, then put a purpose built louvered cover over that block on
both sides and stucco it in when they stucco/parge the wall.

I used a garage door threshold seal and some liquid nails.Â* Mike Holmes would tear out the slab and pour a new one.

There is if you build it that way.

That is the puzzle. I could remove the concrete block wall,
install a series of drains, cover the drains with styrofoam
blanks and then pour a new concrete wall which would then
have pockets for the drains.

Go for it ! Don't let us stop you - after all
you were looking for the "easiest solution " ... duh.

If the wall is otherwise OK, why would you do all that instead of renting
a concrete saw and cutting off the end of the patio where it meets the
wall? It's one cut with the saw, no? And HD and similar have troughs
and grate covers that fit 4" pipe.

What's on the other side of this wall? Where's the water going to end
up going?

If it's just a block wall unless they infilled it, you can just poke the
drains through it.

Certainly w/o seeing the situation it's difficult to say anything truly
definitive...post some pics somewhere...

Yes, also unknown is how much water? If it's just 1/2" that's left
after a rain, just drilling some holes to give it a way out might be
enough.

My one idea was the exhaust vent of a clothes dryer. Knock out the
little flaps if appearance is an issue and put one on each side.

They make a fart fan vent cover for 3" and 4" ducts that just have
small fixed louvers. (Metal or plastic)
