When it is in the range of a sensory/Byakugan user can it be actually sensed pretty easily as Itachi needs to focus chakra on his eyes to use any kind of visual jutsu. Nagato was able to sense that Itachi was going to use his Amaterasu in chapter 550.
 * "Itachi can cast genjutsu not be sensed while casting it not be sensed after plus has the genjutsu speed to trap minato in it."

You can see in chapter 549 that Itachi told Bee not to look into his eyes after Bee was already caught in the genjutsu.
 * " Not looking in his eyes is useless since bee got caught in genjutsu despite not planning on looking in eyes."

Almost every ninja has counters to visual genjutsu. Smoke-bombs are something every shinobi should have, everyone could just stop looking at his eyes and Minato has still Sage Mode as an option to counter all of Itachi's genjutsu, he could just stop opening his eyes and sense everything. That is a huge counter, something he shouldn't even need though as there are still other ways. Minato has the speed and instant teleportation to keep moving out of Itachi's sight and that would make every usage of visual genjutsu useless and a waste of chakra.
 * "Minato can have million jutsus filled with contract seals and summons and speed none are going to work against him. Everything in his arsenal are useless. He has no counter to genjutsu."

Genjutsu being superior to Bee's reaction speed?? What?! Bee was warned to not look into Itachi's eyes when he was already caught into one of his illusions, therefor do Bee's reflexes have no relevance for this discussion in the first place and could you show me the panel or give me the chapter number, where he explicitly states that Bee's reflexes were superior than his??
 * "Genjutsu speed is superior to bee reaction speed which is superior to minato reflex speed hence he'll be caught. He admitted inferiority in reflexes to bee btw. No going around that fact."
