How do you get the OPL Split 1 Finals Icon?
It was a mission or event reward. Riot's description in the client reads: “Earned by completing the OPL Split 1 Finals 2019 mission or purchased in store”
Is the OPL Split 1 Finals Icon still available?
No. Riot tied the OPL Split 1 Finals Icon to 2019 (mission reward), and it does not normally bring back past event rewards or bundles.
