Disadvantage: storytelling talent, reportedly? (9)

I believe the answer is:
liability
'disadvantage' is the definition.
(thesaurus)
'storytelling talent reportedly?' is the wordplay.
I cannot really see how this works, but
'talent' could be 'ability' (I've seen this before) and 'ability' is found in the answer.
The remaining letters 'li' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for liability that I've seen before include "Financial obligation" , "Indebtedness" , "duty" , "Millstone" , "Hindrance" .)
