The Danzo fight could be classified as a plot armour due to these simple facts:

1. He was always suspicious of the Uchiha as he knew their true potential for evil and mental instability. He knew how powerful they were. So Danzo being careless even after using 4 or 5 Izanagi against an MS-wielding Uchiha makes no sense whatsoever.

2. Danzo was old and experienced enough to have detailed information about Susanoo. After all, he lived during the time of Hashirama and Tobirama. Even though he probably hadn't seen any Susanoo with his own eyes before he encountered Sasuke, he knew enough (through Hashirama and Tobirama, as well as through itnel on Shisui & Itachi) to realise that Susanoo is an ultra-haxx technique which you don't fuck around with carelessly. Again, the way Danzo fought, with all his experience, makes no sense whatsoever.

3. Danzo is also reasonably shrewd and smart. After all, he did all the dirty work that Konoha presumably required, in his eyes at least. That requires the ability to handle all sorts of intel, analysing them and deciphering the hidden threats to Konoha. Even Hiruzen, the second-strongest Hokage after Hashi, couldn't prevent Danzo from forming his own personal ANBU, who only answered to Danzo and no one else. It's totally illogical that a shinobi who possesses such intellect would waste precious sharingans by attacking a Susanoo with a kunai.

TL;DR: The way Danzo fought against Sasuke makes no sense whatsoever.
