It seems to be 行こうとする(to try to go) in the volitional form, so it would mean
'let's try to go' and not 'let's try to try to go'.

And since it is incorrect, how would we say "let's try" (with the nuance of
ようとする and not with the one of てみる)?

question
grammar
Why would 「行こうとしようよ」be interpreted as "let's try to try to go"?
行こうとしよう can mean something like "let's pretend to go" or an archaic way of
saying "he will probably try to go".

Either way, that's out of question for the choice in the source.

As for translating "let's try", you could say 努力しよう、挑戦しよう、とりあえず やろう beside
やってみよう, as the comment says.

answer
行こうとしようよ sounds slightly off. If you want to say “let’s try to go” you cd say
行ってみようよ. If for some reason your goal is to communicate an intention to
_attempt to go_ instead of actually just going (which puts us in metaphysical
hair-splitting territory), then you cd say 行く努力をしよう but I have trouble
imagining what context would require that (行ってみる努力ぐらいはしてくれてもいいだろう (“you could
at least do me the favor of making the attempt to go”) or something?).
