Particularizing to the ground state, Kohn-Sham DFT is, at base, the decomposition of the Levy-Lieb functional (putting aside to a separate discussion the issues associated with the original Hohenberg-Kohn and later Levy-Lieb functionals) into physically recognizable, interpretable, and computable parts. Orbital-free DFT (better called one-orbital DFT) exploits only the decomposition, while conventional Kohn-Sham DFT also uses the Kohn-Sham orbitals explicitly. Both variants (to use a currently prominent word) are fundamentally Kohn-Sham theory. Both have the same definitions of kinetic energy, Hartree energy, exchange energy, and correlation energy. All those definitions depend upon the Kohn-Sham determinant. The distinction between those two variants is operationalnamely, what is done to exploit the Kohn-Sham decomposition computationally. This is crucial because of the many statements that one sees to the effect that orbital-free DFT is an "alternative formulation of DFT" that avoids the problems of Kohn-Sham theory, etc. That completely ignores the underlying Kohn-Sham logic. That logic is in fact crucial to constraints on approximate kinetic-energy density functionals (KEDFs).
