Would this yield some kind of grignard-like compound? Or would the hydrogen be reduced?

I know that di-halomethanes will give CH2(MgX)2, although yields may not be great.

It does start by referring a study that stated CHCl3 and CHBr3 did not react with Mg in ether. It seems to be saying that they will react in
situations where the Grignard is prepared in the presence of something that reacts with it,'

ook thanks!

It seems that multiple Mg per molecule, or low H:C rations, lead to the formation of polymeric glorp, magnesium carbides, carbon, magnesium halides,
di-alkyl magnesium compounds, and other stuff; typically in a mismash mix. Having something the Grignard will react with allows for the trapping of
the Grignard before it undergoes those other reactions.

An interesting aspect of magnesium chemistry is that mixtures of it with halocarbons like chloroform can be explosive.
You might want to bare that in mind.
