I think that means it was installed from somewhere other that the
repository, probably one of the precise repositories that you had
enabled.  The problem is that I fear it will want to remove lots of
stuff if you remove it.  Try a simulated remove (which won't actually
do anything).  The -s means simulate

sudo apt-get purge -s liblcms2-2

If that says it would remove loads of good stuff then come back again
for advice.
