Largely outspoken, in trouble and kind of green (7)
I believe the answer is:
avocado
'kind of green' is the definition.
(shade of green)
'largely outspoken in trouble' is the wordplay.
'largely' means to remove the last letter.
'outspoken' becomes 'vocal' (synonyms).
'in' is an insertion indicator.
'trouble' becomes 'ado' (both can mean bother or commotion).
'vocal' with its last letter removed is 'voca'.
'voca' going inside 'ado' is 'AVOCADO'.
'and' acts as a link.
(Other definitions for avocado that I've seen before include "Dark green fruit like posh pear" , "Dark green pear-shaped fruit" , "Evergreen" , "Tropical fruit with a yellow creamy flesh" , "Tropical salad ingredient" .)
