Yes, the square brackets are part of file pattern matching ("globbing",
in the shell jargon) syntax, so need quoting.  Zsh just happens to be
more consistent about this than bash in the default mode (either it's a
pattern that needs to match something or it isn't and doesn't).  It's
not a bug.

If you want the bash behaviour --- where it simply ignores the pattern
if it doesn't match --- you can put

setopt nonomatch

in you ~/.zshrc.

I don't know what the oh-my-zsh attitude to this option is, but I'm
pretty sure there's no implication there of complete bash compatibility
out of the box.
