With the Live images, the OS is in LiveOS/squashfs.img,

much exploring to be done there without extracting or

With a plain iso it would be as easy as

iso-info -l myiso.iso

but for the livecd you have to go inside the squash fs with

iso-read -i myiso.iso -e /LiveOS/squashfs.img --output-file isotmp; unsquashfs -l isotmp

and it is still not enough since you have a filesystem inside, so

iso-read -i myiso.iso -e /LiveOS/squashfs.img --output-file isotmp
unsquashfs isotmp LiveOS/rootfs.img
e2ls squashfs-root/LiveOS/rootfs.img:/usr/bin -l

all done in a freshly created dir with some space, which you will remove at the end.
Unfortunately this can't be done in a single pipe without intermediate files.
