While this is empirically true at the moment (rare for Trump), it is mainly because the courts struck down the NC map and the Republicans are trying to figure out how hard they want to press in Florida and Ohio. Florida's state legislature map is now before the state's Supreme Court, and they're probably waiting for that signal before moving after battling in court over both maps the last time around.
In Ohio the Republicans have already lost one state Supreme Court challenge, and they're probably trying to decide whether to pass something fairer or deliberately pass nonsense again and have that struck down. They could then pass nonsense through the "bipartisan" state commission that they control 5-2, have that struck down, and then just pass whatever nonsense they feel like through the state legislature and have it stick.
The catch is that the nonsense would only stick for four years if it passes, at which point they would have to do it all over again. They could beat federal challenges during that period by just dragging the whole thing out. Interesting way to run a railroad.
North Carolina is probably the original redistricting sin of our times, with Mel Watt's old seat having been battled over in the courts since the early '90s. It was originally drawn in a line along I-85 to hook up majority African-American neighborhoods from Charlotte to Durham, and was even more ridiculous than the 'Gerry-mander' of cartoon fame. They've been fighting in the courts ever since. On the last go-round, it got run all the way up the flagpole to the U.S. Supreme Court seven years later, where the unlikely coalition of Kagan (opinion author), Thomas, RBG, Breyer and Sotomayor upheld striking the 2010 map down. Gorsuch sat that one out, presumably because he had just been appointed and his vote didn't matter.
There may be another contested seat here and there that I don't know about, but odds are this round of redistricting will more or less be a wash when the dust settles. On paper, the Republicans looked to have moved a few seats from Democrat territory to Republican territory via reapportionment. Debatably, this is because the Republicans won so hard in 2010 redistricting that they can't win any harder, despite controlling the bulk of the redistricting processes.
For instance, the Missouri House passed a more or less status quo map two weeks ago on the grounds that any map that picks up another seat by cracking Kansas City Democratic voters is a loser in court. They'll be arguing about it on the Senate floor shortly, with the Trumpite candidates for Blunt's U.S. Senate seat vehemently opposed. It's worth pointing out that the presidential vote in 2020 was 57-41, yet the Republicans control 75% of the seats and are discussing trying to push that to 87.5%.
