To be fair, they only get a pass because either they've done more powerful non-suicidal stuff on page and/or are said to possess abilities we know are stronger.
In other words: Stop whining, that's been answered a dozen times already.

Hiruzen did do S-class battle stuff, but notably the only S-class jutsu he did was a suicide jutsu. Like any limited-use jutsu, that has limited application.
He did show large amounts of battle savvy and array of jutsu, but that fits in S-.
Fighting an army seems like it'd be a really, really hard thing for him to do at this point.
