LLMs give you the boring (i.e. statistically probable) answer. You could probably get it to say "money" almost regardless of what the original question was because it's so generic. It might even say that for a name without all the right letters.

Let's save a tree and ask bash:

$ grep ^.....$ /usr/share/dict/words|grep -i ^[AnthonyMouse]*$

From the more than 300 possibilities we can then consider the context. We're talking about Microsoft here, and the problem suggests we're the sort of people who expect anagrams to have secret meaning, so we should prefer an answer implying some kind of conspiracy or kabbalistic nonsense. The obvious candidates are therefore mason and Satan. Between these, Satan would require reusing a letter the candidate set only has once, and one of the other words on the list was stone. We can form two five letter words if we're allowed to reuse letters and thereby get stone mason.

This is the most irrefutable possible proof that we're being pointed to a masonic conspiracy rather than Microsoft's usual popular association with the antichrist.
