Gucci created Trap Music bro just accept itGucci is no doubt influential, but "trap" isn't a style that Gucci made up. T.I. broke through the mainstream with that style back in 2003 before anyone even heard of Gucci. T.I. gave it an identity and helped establish it sonically with DJ Toomp.
Late 2004 is when you had Gucci and Zaytoven and Jeezy and Shawty Redd come through and upgrade it sonically. It wasn't as complex lyrically as what T.I. was doing, but more so along the lines of Ghetto Mafia was doing years prior.
2009/2010 is when Gucci started pushing what became THE trap sound. Beginning with Lex Luger, all of these other producers that Gucci was discovering started the influx of trap producers. Everybody started mimicking the hi-hats and the drum patterns to the point that it became the dominant sound in Hip Hop. From there it spread to the Euro club scene and spawned EDM trap. Now you have Pop stars using the sound too.
