泣けばいいと思ってて綺麗事ばかりな主人公にイライラする。


The excerpt in the title of this question is a comment someone made about a
manga I’m reading, ブラックジャックによろしく.

I have two questions:  
① What is the て preceding **て** 綺麗事 for? Is it a typo to have two て like that
in succession?  
② Is イライラする an example of a verb which is based on mimetic sound?

The `て` preceding 綺麗事 is the て-form of the auxiliary verb `いる`. Dropping the
`い` in `ている` is very common in colloquial speech, I.E. `思ってる`. This just gets
slightly more confusing with sequential て-forms. You might think of it like
this:

> 思う ー＞ 思っている ー＞ 思っていて。。。 ー＞ 思ってて。。。

In this case the second `て` is just there to let the person continue their
sentence. So for the sentence below

> 泣けばいいと思ってて綺麗事ばかりな主人公にイライラする

A very, very direct translation might look something like this:

> (They) think it will be fine if they cry and are all superficial positivity,
> which makes (me) angry.

As for `イライラする`, it's certainly a mimetic. `mimetic+する` is a sufficiently
common pattern that I don't think if I would call this a "verb based on a
mimetic" as much as just a normal mimetic; the `する` here just describes the
action of being in the state associated with the mimetic.

Edit: Please note my original interpretation of the sentence was incorrect as
I misinterpreted the omitted subject for `思う`. I'm using
[naruto](https://japanese.stackexchange.com/users/5010/naruto)'s provided
translation here

> The protagonist thinks weeping solves everything and just talks about
> ideals, which pisses me off.
