The state of US case law -- IANAL, this is a layman's understanding -- is that plaintiffs only have to show that there exists "disparate impact," which is to say that outcomes were not exactly the same for Asians/whites and blacks.
Two things can be true: 1) Google did not intend to discriminate, did not institute any policy designed to discriminate, did not in actual fact discriminate against non-Asian/white employees; and 2) they could still be held liable for hiring results that look like discrimination in a single-variable analysis.
So, yes, I think there are indeed situations in which they'd pay out settlements knowing full well they've done nothing morally or ethically dubious.
