They were not very good in the second half I didn't think. Turned the ball over a lot and looked far less dangerous without pulisic. However playing a little lazy up 3-0 is understandable. They can play similarly against Australia but strategy will need to adjust against better teams. They took a ton of chances and left themselves exposed a lot in the first half, Paraguay just wasn't talented enough on either end of the pitch to do anything about it. Playing that way against a top 10 ranked side probably results in a 3-0 halftime deficit instead of a lead but I believe coaching is smart enough to know that. Definitely a very entertaining first half and was super important towards gaining momentum with casual fans. I personally didn't like the commentating style because I felt like they tried really hard to commentate for people who don't typically watch the sport but I understand why they did it. Great start for the team and country they should be in the driver's seat to top the group and I would expect a comfortable win against Australia too if pulisic is healthy.
