I typically find i can only toss out my instant casts towards the end of a movement phase for this reason, and because the boss does this 4 times in a row, there isn't enough "breather room" to use any abilities until the mechanic is over with and someone has probably either died to the aoes, the poison dot, or the spread markers.
Which keyboard buttons would be easy for you to press while you're moving around using WASD? You could remap those keys and put your big AoE instant tools there, so you can press them while running without having to fiddle with mouse cursor etc. I tend to move a lot using just mouse and have all my "emergency buttons" on 1-6, meaning I can just press a button (or piano multiple if needed/panicked) and get the casts off consistently. Whatever is comfortable for you can work - you have entire keyboard to work with, and there's few buttons very close to WASD that should be easy to press - QERFCV for example. No harm in trying - maybe there's setup that'll be more comfortable than what you're currently running?

Also, regarding your screenshot, you're standing very far away from the boss, at an awkward angle - including camera angle; dodging a cleave followup from here would require you to run all the way to the boss, through them, and at this angle carefully mixing W and D inputs so you don't run through poison (or rotating the camera, which fully occupies your mouse). See where rest of your party is standing - next to the boss in a spot where dodging big cleave can easily be done by just running through. You know the mechanic, you know where you'll need to move - if you preposition yourself and camera in a way that lets you dodge by using just single button (right next to the boss, looking directly north - in which case A/D are only buttons you need to dodge safely), pressing or clicking other buttons while running will be easier - you don't need to rotate camera, you don't need to run around a hazard, you're moving in a straight line. The trick here is to be proactively lazy - the less you need to do during mechanics, the lower chance something will go wrong; park yourself in a spot where you see everything you need and can move as little as possible, pressing as few buttons as possible.
