I think you were trying to make the status depend only on what was
before the first "&&".  You can certainly do

first-statement && {
   any-old-stuff
}

and it does have the effect of "if", though there's no obvious reason to
prefer this form (some old shell code is indeed written this way).  The
key points are

- the open brace is the first thing after the &&
- the close brace is after the last thing you want controlled by the
status of first-statement.

The real point, perhaps, is to be able to separate out that
any-old-stuff as something contained within the block, however
complicated it is by itself, so you may just have been getting
distracted by pipelines and ||s etc.
