Of course not, but what's the point? Who complains that Signal doesn't run without Google Play Services are the kind of users that wants to run a mostly free distribution of Android (like LineageOS) without any Google software on it. Saying well you should buy a more closed and proprietary system that can run Signal without Google software is nonsense.
Luckily for those users, Signal does run on mostly free distributions of Android without Google software on it - specifically without Google Play Services. I do so.
