I don't think a separate adv-to sense is needed.
とどろとどろ is really a separate (archaic) word. I think it can be dropped.
Doesn't appear to be adjectival. Sankoku has it as ト|タル only.

Daijr says it's wasei, but the term is used in English a bit.

perhaps should be specified that it means doing it casually (e.g., for friends) rather than "professionally" for profit?  i didn't look at the refs to see if this is indeed the case.

As the chiebukuro discussion (above) shows, it's hardly recognized in Japanese, and may indeed be a mistaken/jokey form of めちゃめちゃ or むちゃむちゃ. Also it's pretty uncommon as a 擬態語. I think I'll just drop it, and it can be revived if some authoritative information comes up.

Your call, and I have no problem with it.

'Mumblingly' sounds reasonable too, though it would have 
been redundant in my translation (as I have found many such 
onomatopoeia to be).

Thanks for posting the example.
Before adding this to the dictionary we need more evidence than just a single example.
The translation "sheepishly" is possible, but so is for instance "mumblingly".
It is a bit confusing that according to the ngrams もちゃもちゃ is often used with 食べる.
I think we should leave this open for a while and see if anyone comes up with something.

In Takemiya Yuyuko's "Golden Time 5", page 68, we find 
the following text:


いつもの完璧美人ぶりなど見る影もないほど硬く顔を引きつらせながら、そ
れでも香子はリンダが貸してくれた口紅のキャップをなんとか取った。ありが
とうございます、どうもすいません、ご迷惑をおかけして、みたいなことも口
の中でもちゃもちゃ言った。恐らく誰にもはっきりとは聞き取れなかっただろ
うが。

My current rendering of this is: Kouko was a mere shadow 
of her usual perfect beauty, her face stiff as if 
cramped, but nonetheless she somehow removed the cap from 
the lipstick that Linda had lent her.  Sheepishly, she 
mumbled things like ‘Thank you very much’, ‘I’m so sorry’ 
and ‘I’m being such a problem for you.’  Probably nobody 
caught what she said, though.


As context, the girl Kouko had just made a fool of 
herself in front of everybody with a sort of panic 
attack.

Nonetheless, if you think this one is too rare, that's 
your call.  It's your database, not mine.

A bit of random googling suggests that it means "sound of eating noodles".
But the ngram numbers are very low, so I think we can skip this entry
