[lammps-users] multicomponet substrate and deposition

LAMMPS can't generate such structures, but it can input any
structure you wish from a data file. I think you'll have
to find or write a program that generates the amorphous
substrate you want. If there is a Ti + C lattice with the
stoichiometry you want, you could run it at high T to generate
an amorphous sample.
