For phones that have a dedicated hardware module, such as the Pixel 3, yes the key material is generated and stored there. Using it requires a physical action that is hardwired to the hardware module.
We think the most pressing need right now is to protect users against phishing, which is a much larger threat than malware. Thus we think there's a lot of value in enabling this for all phone models where it's possible to run the protocols.
(I'm the TL for this at Google)

Because the squeeze function on Pixels or assistant buttons on other devices could be used instead, though that's just me wondering out loud for an alternative user-facing implementation because the use of volume button seems strange to me.
