Regardless of whether it's slower (which I expect someone will be along to debunk or explain shortly), do you really want to have to write an additional boilerplate function or block of code /every single time/ you want to do such a check? The runtime speed difference is unlikely to be worth your time as a developer in many cases. And by Murphy's Law, you *will* make errors writing these repetitive code blocks (e.g. forget to negate the conditional), whereas reusing all() makes that much less likely. The trade-off is run-time speed for developer productivity/convenience; Python tends to lean towards the latter (to varying degrees).
