Can e.g. TLA+ help with that at all?

If you want to see what TLA+ specifications of distributed systems look like, there's this lecture series, each on a different distributed algorithm: https://github.com/tlaplus/DrTLAPlus The kind of bugs you find when verifying distributed systems is, if this machine was in that state and that message was in transit, and then the other machine failed, then data was lost". Basically, because formal verification of this kind ensures the specification is correct, it will find any kind of bug there is. But it's those bugs that are either a result of a severe flaw in the design, or bugs that would be hard to find in testing but their results may be serious, that make this worthwhile.

No; not yet, at least. But this is a lecture series about using TLA+ for distributed algorithms: https://github.com/tlaplus/DrTLAPlus There's also a Coq framework called Verdi (http://verdi.uwplse.org) for formalizing distributed systems, but I don't know much about it.
