  * speaker has gotten informed that a bunch of girls have gotten interested in him 

what does と serve in this sentence, why not から？ It seems to be a bit of a
stretch of be quotative.

thanks




「～と[化]{か}する」 means "change~~" "turn into~~". The と has almost the same
function as 「に」 in 「～に変わる」 or 「～になる」. (For the difference of 「～になる」 and
「～となる」, see this thread: [What is the difference between 〜 **と** なる and 〜
**に** なる?](https://japanese.stackexchange.com/a/739/9831)

> しかし［（今の俺には）無用の長物と化した］それ

今の俺には literally means "for the current me" "for what I am now" (≂ 今の俺にとっては).
今の俺には無用の長物と化した is a relative clause modifying それ, and それ refers to （遅れて来た）モテ期.
This line uses 体言止め (See: [what exactly is
"体言止{たいげんど}め"?](https://japanese.stackexchange.com/q/14524/9831)). So it's
literally saying "But it (= my モテ期, which arrived late) has turned into 無用の長物
for the current me."
