There is no need to have "NAND gate only" ICs in CMOS. You can easily implement any AND-OR-only network followed by an invert (NOT) gate for the output. As a further example, pass transistor logic is an alternative which can be implemented using CMOS transmission gates, it does not use a NOT stage however this means that it will not restore the signal voltage for the next stage, unlike the usual sort of CMOS logic.
