Think of it quantum mechanically, God is aware of all possible outcomes, of which Adam lying to Him was but one of the many possible consequences of free will (note that the forbidden fruit gave them knowledge of their nakedness, they already had free will). Free will is inherently incompatible with determinism unless we account for all possibilities resulting of free will. Quantum mechanics and superposition theory is the closest we can get to understanding the machinations of God. Even then it still doesn’t help in the least.
