I would make sure once more that there are no LJ params by checking the 
tpr file:
gmxdump -s topol.tpr
then look for the atom types of your atom
should find it, and when you know which atomtype T you need search on
that will bring you to the LJ parameter matrix in which you should check 
entry (T-1)^2
