Most of this questions are better suited for the Tor mailing lists than
here.
Anyways, my 0.02 cents is avoid torify / torsocks / whatever thing that
relies LD_PRELOAD. In OpenBSD, you don't need any port to connect with
ssh to Onion services; nc natively supports SOCKS5. The following will
work magic in your ~/.ssh/config:
Host *.onion
ProxyCommand /usr/bin/nc -X 5 -x localhost:9050 %h %p
