You are right, L2 is OK. It looks like it leaves bad aji 
compared with L3 but actually W can't do much.

After B:L2, W:O3 B can play K2 and W can't do anything. It
could get a little complicated with something like

B:L2 W:O3 B:K2 W:P2 B:N3 W:O1 B:Q1 W:P1 B:M1 O:O4

but black wins the semeai by one move.
