Why is ESI (ISFj) the aggressor and not the caring type in Gluenko's erotic attitudes?

Because they have Se. Erotic attitudes are related to irrational functions in the ego block.

The theory is actually incomplete, there should be erotic attitudes for rational (base) functions too, because they modulate the person's response to the environment.

And what I mean is how exactly does their Se ego (ESIs) affect them in their behavior so that they are considered aggressors.

Yes you're right, socionics is a descriptive theory (as Jung created his functions based on behavioral descriptions) and thus we do not have a clear answer as to "why someone behaves in such a way due to being Se ego".

I can't help you with this But I agree that ESI show a lot of "caretaking" behaviors in the lexical non-socionics sense. Especially subtypes who are less strong on Se.

She also likes a man who thinks quickly on his feet and shows mental acuity. If you have all of these characteristics, then, there is no doubt, that she will make you marry her sufficiently quickly, because DREISERKA is a girl marked by drive and determination; she follows through with her goals. And she never steps back from her purpose.

LIE and EIE can sporadically display good usage of Se, but ultimately strength in the 2D functions are weak and all for show. Once you know the Hidden Agenda and Role functions of a type not much will appear contradictory in the descriptions.
