Illaoi can be a pain, but I still reckon you stand a good chance overall.
Be mindful of her tentacle locations, don't let her poke you for free, and take advantage of your ult post-6.
If she manages to grab you spirit with her E, don't just walk away and let her beat it up for free, try to hit her with your E-Q combo when she starts to beat it up.
