The base idiom is: to take notice
You can often take any verb that collocates with a noun, and add "for all". But not always. This usage of for all usually involves perception, effort, abstraction of some kind or some other "force".
For example, here are some which come to mind: to take the trouble to do something, to put effort into something, to display courage, to counter arguments, to show weakness
All those kinds of expression can take for all.
- for all the courage he displayed
- for all the trouble you took
- for all the effort we made or put into x
- for all the weakness she showed
- for all the noise they made [noise=metaphor]
In the OP's example, for all the notice anyone took means, nobody took much notice of whatever it was. This "for all" can be used negatively or positively.
You should be rewarded for all the trouble you took.
She should be reprimanded for all the weakness she showed.[police officer, for example]
It means: given the amount of x used, or given how much x.
