I just tried this with a private key with passphrase.  It worked.

  lftp :~> set sftp:connect-program "/usr/bin/ssh -a -x -v"
  lftp :~> open -p 22 -u corinna sftp://linux-box
  lftp :~> notice: cannot open /home/corinna/.netrc: No such file or directory

  lftp corinna AT linux-box:~> ls
  drwxrwxr-x   10 corinna  vinschen     4096 Feb 24 11:36 .
  drwxr-xr-x  103 corinna  vinschen     4096 Feb 24 11:28 ..
  [...]
  lftp corinna AT linux-box:~> quit

Did you try if this works with the latest Cygwin snapshot from
http://cygwin.com/snapshots/ ?
