No; Bill Evans and Gil Evans are two different people

I know. But the parent said:

You can even say "Kind of Blue" is a Evans' LP by how much his influence on composition and arrangement is strong,

And Gil Evans did the arrangements on two of Miles' influential albums that preceded Kind of Blue, namely Miles Ahead and Porgy and Bess.

Yes, but Bill Evans did the arrangements on Kind of Blue; he is also rumoured to have composed several of the songs (although they are credited to Miles.)
