I don't know what's Montagnier's position beyond that paragraph on Wikipedia, but a virus undergoing gain of function research could be I suppose described as "deliberately created" (obviously not from scratch and not deliberately released).

That said, Montagnier appears to have speculated that SARS-CoV-2 contains genetic information from HIV. That seems almost surely false, since the sequences he cited occur frequently in many organisms.
