First, something to clear up: The true name of Esnare / Root should be Esnared, which is used on MOBAs, such as LoL; for reasons unknown to me, despite in-game says "Esnared" upon being disabled by such, the community has adopted the name Root.

Second, about Blind / Disarm: In the other MOBAs in which both effects coexist individually, they still possess Miss chance (LoL had it, but Riot eliminated it), which make the existence of both make sense, Blind makes attacks fail to strike the target and Disarm, like Silence is to abilities, disables autoattacks; however, in such games Blind, unlike our version of it, doesn't guarantees to make attacks miss (Normally from 30% to 75% chance they apply) and needs to be stacked with other sources of miss chance, be this Evasion, but again, Riot eliminated it (Because is based on a P-RNG  engine, the only one remaining in-game with it is Critical Strike Chance), so they make LoL's Blind have a 100% chance to make the target miss, which acomplishes the same function as Disarm, that of inutilize autoattacks.

And about the confusion with Disarm and Entangle, here are some concepts: Disarm (DotA / DotA 2) , Entangle (LoL) and Entangle (DotA / DotA 2).
