'broke everything' is the definition.
I can't tell whether this definition defines the answer.

'little kid from italy' is the wordplay.
'little kid' becomes 'tot' (tot can mean a young child).
'from' indicates an anagram (from the letters).
'italy' anagrammed gives 'ality'.
'tot'+'ality'='TOTALITY'

Can you help me to learn more?

(Other definitions for totality that I've seen before include "Tilt a toy (anag.)" , "Whole thing" , "The complete number or amount" , "Whole amount" , "Sum" .)
