Pitch Accent of 何にも


I'm trying to understand the pitch of the sentence fragment

> それであたし何にもしてないのに...

In particular "何にも" is giving me trouble. When I enter this word into
[OJAD](https://www.gavo.t.u-tokyo.ac.jp/ojad/phrasing/index), it shows as
Atamadaka:

But dictionaries are reporting it as all sorts of things:

Moreover, it looks like the reading of "何" from "何にも" can be either なん
(slang?) or なに. If the latter, the pitch changes again?

Finally, is "何にも" distinct from 何 + に + も? If not, an accepted pronuncation of
何 seems to be "naNI" (Heiban), so wouldn't a third acceptable pronuncation be
"naNINImo", since the first particle would raise (since 何 is being treated as
Heiban), and the second particle would lower (since second successive
particles lower, as a rule)?

At least when 何にも is used as a [negative polarity
item](https://japanese.stackexchange.com/a/16060/5010) (which is almost always
the case), it is always pronounced as heiban (なんにも【LHHH】/なににも【LHHH】). That
result from OJAC seems confusing to me.

But なににも【HLLL】 may appear in rare cases where it is used as an equivalent of
何にでも/何に対しても (e.g., なににも【HLLL】使えるソース "sauce you can use for
whatever/everything").
