Hey there.. need helps here..
The question is..
Derive an expression relating the output voltage, Vo to the input current, Iin.

i try to derive it.. but..
got problem with RL
V1 = -IinRf
Vo =- R2/R1(-IinRf) how to include Rl in my derivation?

Everything is correct.
If A2 is an (ideal) opamp with (nearly) zero output impedance, RL has no influence on the output voltage.
