It does look like someone was a bit rough on the connector. Here's an image of the main logic board which you can compare yours to: [https://d3nevzfk7ii3be.cloudfront.net/igi/Ik5Fl6oZmmIw1Brg|13" MacBook Pro Retina (Early 2015) Logic Board].
At this point I think your issue is more likely the cable that goes to your trackpad or the trackpad logic where the signals for both the keyboard and trackpad come together.
Did you spill something onto your system or put it down on a wet surface?
