Is there any reason why the anime adaptation somehow has longer title than its source material?

Adding "bunny girl" to attract potential viewers. :P

It's not, you can see it in the LN picture - it's the same title as the anime's, but whoever made the tag used the concatenated version of the title.

It's the first volume of the novel

The rest of the series use title pattern instead of volume number.
So it"s "Seishun Buta Yarou wa [something] no Yume wo Minai"
Such as Logical Witch, Yumemiru Shoujo, Odekake Sister, Hatsukoi Shoujo (Uiharu!?), Siscon Idol (Elf!?), Petit Devil Kouhai
