Not sure if before '04 it was standard, but for '04, the LS430 came with TPMS as standard. Keep in mind, it does not measure the pressure directly from the valve stem like on the LS460, it measures using the ABS system and measures tire rotation and differentiation from last "reset" or initialization.

I think that if somehow both of your fronts let's say are losing pressure at the same rate, you will not trigger a low warning. Also, the pressure loss in each wheel has to be under 26 psi. It's really measuring for "gross" pressure loss, not a variance of 6 psi. I mean, I could be wrong.

Since the pressure is not measured directly, I went and got myself a set of four (4) "Tireminders" for measuring the 30-33 range. So, if the pressure drops below 28, I'll be warned.
