The Greek Septuagint (LXX), 132 BC; the Dead Sea Scrolls (1QIsa), 125 BC; Codex Sinaiticus (Greek), AD 330-360; Biblia Hebraica (Hebrew) Stuttgartensia (Leningrad Codex B19a), AD 1008-1010; all say "wolf." There are no versions of the Bible that read "lion"
Isaiah 11:6 (KJV)
6 The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them.
What’s your thoughts is it lion or wolf?
