Top Law Schools

Hello! So I felt lucky to have had two LORs from the previous semester already, but I noticed that the schools I was applying to at least mentioned that getting a letter from this semester would be a plus. I just finished my last final today and this final was for the professor I talked to the most this semester (which doesn't really say much since half of the semester was online). I did really well on the midterm, and he plans to grade our finals so that we can know how well we would have done. I'm debating is it too late to ask for a LOR? Would it be that beneficial to ask?

For context, I'm applying HYCCN, currently TT with a 4.06.
