Who Wins

Pre-6 you win this lane convincingly at levels 1-2 because your W shield absorbs Illaoi's E tentacle slam entirely and your Q knock-up lets you dictate trade length; at level 3 you still have the edge if you manage W timing correctly, but Illaoi's tentacle density starts to matter.
Post-6 the matchup becomes genuinely dangerous — Illaoi's R spawns tentacles that ignore your W shield and her healing scales with the number of tentacles hitting, so you must avoid fighting her in a tentacle-dense area at all costs.

Your best pattern is to W pre-emptively as you walk into Illaoi's E range, absorb the tentacle slam with the shield, then pop it aggressively into her face to deal burst damage and force her to back off before her tentacles can chain-slam you.
Short trades heavily favor you because your W shield resets the damage equation; never let the fight drag long enough for multiple tentacle slams to accumulate.

You want to hard shove the wave early and repeatedly to deny Illaoi the ability to set up tentacles around a stationary wave, because tentacles only spawn near her position and a fast-moving wave forces her to choose between farming and positioning for trades.
Crashing waves also lets you back safely and denies her the slow-push setup she needs to make her R lethal.

Do not use your R to engage into Illaoi when she already has her R active — you will charge directly into a field of tentacles, your unstoppable state means you cannot cancel the dash, and her tentacles will slam you repeatedly during the entire duration of your R channel.
Your R is better used to escape a losing fight or to engage from outside tentacle range when she has no R available.
