Which OpenSSH? Cygwin's? Does it generally work?

Should be 0700. And, did you also change its ownership and that of all
files inside to the Jenkins user?

Don't know why you think you need to use -t, though. However, you NEED
to provide the private key: -i /path/to/keyfile. BTW: This will not
execute any command on the remote host, since you've spilt it into
separate lines. So the correct command would be:
ssh -i /home/jenkins/.ssh/great.key jenkins@x.x.x.x 'echo "something"
>foo.txt'

That might come from the wrong .ssh directory permissions, see above.

Fix the .ssh directory (and contens) permissions. Make sure the
connection generally works (from outside Jenkins). You also need to log
in once manually (as the Jenkins user on Linux), to have the host key of
the Windows host added to its known_hosts file.

Well, you can't (it's a Windows thing, hence the name CygWIN).
