You just want to run "otool -L" on a large number of files?
Open up a terminal window and go to the directory containing the files, then type this:
for f in *
otool -L $f
OSX is a unix based system, and "terminal" is a unix shell that allows you to run unix scripts.
Google "Unix shell scripting" to find out more about shell scripting (also, do that if there is a problem with the syntax of my solution -- I didn't have a Unix machine to test it on).
