Well, if your definition of LPR is anything under Level 1, the Sheri's Hot Rockets Shuttle is likely a good candidate here.
Chan Stevens had built hundreds of rockets, but he had a heckuva time with the Shuttle:
"Let's get this much out in front--this is a skill level 4 or 5 kit, not for the faint of heart or inexperienced modeler. I have over 400 rockets under my belt, mostly LPR, and this was much more difficult than I expected, and absolutely kicked my [fanny]. This is coming from a guy that's built several Saturns, including the Apogee V and 1b. It took much longer than I expected, and I wound up with a mediocre finish that I'm not especially proud of. If you plan on building one of these, be prepared to invest a considerable amount of time and set the expectations at a decent, not flawless finish. This is a very nice model, but not likely a museum piece without extraordinary finishing skills." - 3/24/08 Chan Stevens on RocketReviews (https://www.rocketreviews.com/sheris-hot-rockets-cjs-aviation-space-shuttle-162-by-chan-stevens.html)
