John.
You seem to be a little misguided as to how a football club works.
The manager may ask for players, money for players, new shoes for his wife, etc etc, but at the end of the day, the go-ahead will be given to spend the money by the Chairman, on the advice of the finance director [although the Chairman can of course ignore any advice given to him/her].
Culpability will therefore always rest with the man/woman at the top.
However, having said that, it is not reasonable to expect the Chairman to be fully conversant with all areas of the business [except Lowe of course ], so the blame can be shared out between the various 'advisors' - manager, directors etc...
You seem to hold the opinion that the Chairman is completely blameless for anything that happens to the club / company...
