The details from 2020 (only ones I can find) I've seen posted say they have, e.g., a $15k allowance for health insurance, of which only $5k is refundable as cash if not used, and a 5% on top of base “free option” stock option purchase in their ESPP, as well as choice for elective purchase, and other compensation in excess of salary and hourly wage.

OTOH, if they actually are just calling their “base” (which is in fact at least potentially salary) “total comp” when it is isn’t actually total total comp, just closer to total comp than base salary typically is for the industry, that’s probably not a violation of the law.
