Consider the delta-V required to go from LEO to L4 or L5 with Lunar assist.
Is this more or less than the delta-V required to escape Earth completely
from LEO?
It is a few percent more than the energy needed to get from LEO to elliptical trans-Lunar Transfer Orbit.
LTO in turn is a few percent more delta-v than eliiptical geostationary transfer orbit.
These are all a lot less than LEO to GEO. It is the large final circularization burn delta-vee at GTO apogee which is the killer for LEO to GEO.
I have the numbers at home in a spreadsheet, I can post them over the weekend if y'all are interested.
Cheers,
CR.
