'Love is love' is something that's been used in the LGBT community forever to mean that homosexual love is just as valid as heterosexual love (referring to consensual relationships between adults). It's been coopted by pedos and other disgusting people, but the phrase on its own isn't a 'pedo thing'. And the 'it's okay if you're not ready yet' post seems to be about coming out of the closet- That's how I would have interpreted it if anyone else had posted it. Given the context we have now, it's definitely questionable, but I don't think the first two images would have been red flags. The third one ABSOLUTELY, but I'm not sure if that's actually something posted on the IG page or something you added as an example of pedos using 'love is love'.
