We have a gene in the BM streptomyces phage Satis [gp211 with annotated start @129464], with around 40 HHPRED hits with > 99% prob and > 98% coverage with short descriptions of "cold shock protein" and one hit of similar quality to an "RNA chaperone". Investigation into these cold shock proteins suggest they also act as chaperones. See this JBC paper.

I think either a generic "chaperone" or a more specific "RNA chaperone" would summarize the results here. For the recent submission we took the more conservative route of just "chaperone".
