The man pages at:

Do not document an iflag parameter. Is this simply an error in the
documentation? It looks like I'm still using coreutils 5.2, so I guess
I'll have to upgrade. I'm wondering now why there was over a year
between the release of 5.2.1 and 5.92, with nothing in between.

It's in coreutils 5.93 dd. Try, e.g., "dd iflag=direct". It's
not documented with the phrase "O_DIRECT", though, which is possibly
why you missed it.
does dd use aio so as to keep the IO pipelined, since a blocking
read/write would only be able to access one file/disk at a time?
Nope. Might be nice to add, I suppose.
