There is sth quite wrong with this phrase entry 拎他一把.
Firstly, as the OP has pointed out, 他 cannot be pronounced in tone 4 ‘taa4’. Besides, 拎 is almost always pronounced as ling1, never ning4 as now used for the phrase.
Secondly, I might have seen this entry being used as a Mandarin-specific phrase before. It is definitely not a Cantonese phrase as now suggested. Neither is it being used in standard written Chinese. If it is a Mandarin phrase, then it serves no useful purpose to give it a Cantonese reading.
