Pretty sure Bitcoin mining has been ASIC dominated for ~8 years now. Maybe you could point at Eth which only just recently moved away from being GPU heavy.
If LastPass happened to use the exact same primitive as bitcoin this Asic hardware could still be used. Not sure if the case.
Bitcoin's primitive is sha256(sha256(x)). There's zero reason anyone would ever use a funky construction like that for password hashing.
I can see it now: a developer copying Bitcoin code into his authentication library because "Bitcoin is secure"
Furthermore, mining ASICs bake in assumptions about the structure of x as an optimization. I'm not sure they can even be used to hash arbitrary values of x.
Is cracking a sha256(x) the same runtime as sha256(sha256(sha256(sha256((x)))))? I remember the first time I saw bitcoin's double use of sha256 like this, and I was confused as to whether there is a security benefit to this.
