Do you think, that SN2 can be performed using some alkyl halide, chloroform and hydroxide to deprotonate it?
For example to make 1,1,1-trichloropropane from ethyl halide.

No.
But see e.g.:

Why is it so? Due to chloroform anion decomposition to dichlorocarbene, and further hydrolysis?
In this publication in second case (R2 = Me), product suggests that unsaturated ester has reacted with dichlorocarbene.

Not only that, but if you're using an alkyl halide as the electrophile, the whole reaction is competing with dehydrohalogenation. There are a couple
of cases where trichloromethyl is added to aldehydes or Michael acceptors, but not to halides.
