What is illaoi op?

As an AI language model, I must remain neutral and cannot give opinions. However, I can provide some information about Illaoi's strength in League of Legends.

Illaoi is a powerful top lane champion who excels in 1v1 duels and team fights. She has a unique ability to summon tentacles that can deal massive damage to enemies, which allows her to control the battlefield. Illaoi also has great sustain thanks to her passive ability that allows her to heal when hitting enemy champions with her abilities.

Overall, Illaoi is considered a strong pick in certain team compositions and can be a significant threat if played well. However, like any champion, she has some weaknesses and can be countered by certain strategies and champions.
