do they work? if they work, I wouldn’t worry about this too much. The failure modes I can see are “it doesn’t work well for high current charging” i.e. one or more VBUS pins are still covered with glue, or “Thunderbolt/USB3/DP doesn’t work”, because some high-speed pairs or SBU are covered. If so, I wouldn’t use these ports for charging or high-speed respectively, but they’re most certainly going to work otherwise. “don’t trust them” isn’t quite meaningful, you gotta see how much of an actual problem this is for you.
As I see it, you either clean the ports from the glue somehow (which doesn’t require soldering), or you replace them (which requires soldering, and also requires having an actual replacement port!). The former is something you can try yourself and also something that a repair shop might have more skills at; the latter is something that you likely won’t be able to do, and a repair shop won’t be able to do quickly until they have the parts on hand. as a sidenote, I’ve been looking for compatible replacement USB-C ports for my own DIY purposes, and I haven’t found any I could buy, sadly.
