I guess you won't like this response, but you've already identified how
to locate errors: load the file, write it back out, and compare the two.
That is:

2) Run SELECT INTO ... OUTFILE, using the same line and field delimiters
that were used to load the data
3) diff the original input file with the file generated in step 2.

Unfortunately, you cannot perform step 2 unless you have the FILE privilege
on the server.  An alternative is to run a simple SELECT to generate a
tab-delimited output file by invoking mysql --batch.  This may work if
your input file is tab-delimited.
