It isn't that Bash is caseless. You can prove that to yourself by
checking that A* and a* still match different files.
The issue here is that it's localized. You're apparently running in a
locale in which the localized colating order is:
AaBbCc ... Zz
(in which case you should find that any files beginning with a
lower-case "z" survived the removal). Or possibly you're in a locale
aAbBcD ... zZ
(in which case z* files will have gone, but a* files survived).

Not specific to Bash; any program that sorts text should take
$LC_COLLATE into account. Or if $LC_COLLATE isn't set, the more generic
$LANG is used instead.

Doing this will specify collating letters in Ascii order:
