If he auto's, he is threat range for you to catch up. His E doesn't proc trinity/ibg and even if it would, that would be his death sentence, since he's so close that his E targetted you.
I don't know why it has to be 10 champs with better mobility to make him not hyper mobile. I guess the term is open for interpretation, but hyper mobility means something like excessive compared to a certain standard.
No doubt Ez' E is a good mobility spell, probably the best of any adc or one of the best in game, but that doesn't make him hyper mobile. Considering Shaco's Q is a better version of it and you didn't even list him, I assume you wouldn't count him hyper mobile and neither would I.
All the champs you suggested, with the exception of Tryn can use their mobility multiple times in a short amount of itme and aren't gated by 1 single instance. For that reason I would also consider Talon of all to by quite hyper mobile. It's not that he has a better mobility spell than Ez, but an excessive amount of mobility. Q E (honestly, that wall gating is not really as big of a deal) and R inv + ms, mostly his E. Also idk why you wouldn't mention Kayn, whom I'd consider to be the most mobile champ in the game. Who needs a blink if you can literally walk through walls for a decent amount of time.
Going back to Ezreal, I wouldn't consider him hyper mobile, since he doesn't have an excessive amount of mobility ready to save him all the time. Yes his E can make it hard to catch him, but he's still very vulnerable if you manage to get into threat range.
Imo, there isn't an easier botlane to fight than Ezreal atm. Of adcs that is.
