Lakers already acquired Mark Williams from Hornets for Dalton Knecht
While Mark Williams could really fill the gap for AD but I am feeling that letting go of Dalton Knecht is not worth it for them. Well, what's done is done and he's going now to the Hornets and maybe he'd capitalize his talent there. And with all of these trades, look at PJ Tucker, he's traded and went to several teams within just 5 days. 
We really don't know how good Dalton will be in the future, but the Lakers are willing to take that risk for now. So still a win win for them as they got a good big man and then who knows, maybe Dalton will thrive on other teams and take advantage of his shooting,

So Nurkic will be the replacement of Mark Williams, but they are going to lose 2026 first-round pick to the Charlotte Hornets.
Dalton Knecht could indeed be a great asset in the future, but I think even for he could turnout to be a really young center like Mark Williams seem like a steal for the Lakers, I doubt the Hornets would have given up Williams for something not as promising, if not more. This move does help setup Lakers to compete now and while also building for the future at the same time.
