Why did the stand "Notorious B.I.G" change to "Notorius Chase" in the anime?
I haven't gotten to that part of JJBA yet, so this is an educated guess.

Like a number of other characters in the franchise, such as ACDC, Pet Shop, and Jean Pierre Polnareff, Notorious B.I.G. is named after a real-life musician. In a number of cases, these character names are modified in localizations presumably to avoid potential trademark issues. For instance, Steely Dan becomes Dan of Steel, Terence D'Arby is D'Arby the Younger, Kenny G is Billie Jean, etc.

I can only assume that something similar happened here. I don't have access to the episode right now, but this Reddit user suggests the same thing and reports that some of the animation was changed.
