Hey syed.

If you have already completed your Undergraduate degree or equivalent and now you want to pursue law further the you should go for a 3 year LLb degree instead of BA LLb.

As 3 year LLB degree is ideal for those who have already completed their Undergrad in any discipline whereas 5 year Integrated BA LLb programme is ideal for those who wish to apply after 12th directly and those hwo haven't done their UG degree. There is no benefit of doing BA LLb instead of LLb if you have already completed your UG degree. So you should go for 3 year LLb.

Best of luck!
