It's a Chinese team.
At any rate, I think I misinterpreted your question. When you said you wanted to focus on survivability, I thought you meant you wanted to play a bruiser Akali rather than an assassin. Bruiser Akali is sorta a thing that you'll see sometimes in specific team comps {or just goofing around). Triforce is a decent item in that scenario because it givers her HP, more move speed, a better slow, the Sheen proc, attack speed that synergizes with her passive, etc.
If you're looking for survivability on assassin Akali, then Rylai's is probably the most common pick. You shouldn't really be focusing too much on survivability too much though, it's you goal to clean up and pick people off, not to sustain in long team fights.
