AFAIK, the TFM files (and even the master MF files) for the Cyrillic
LA font family are created on the fly. What about explicitly
creating them as a make prerequisite?
mktextfm latt1095
mktextfm larm1095
Note that normally TeXLive is configured to use PFB files from the
'cm-super' font family for Cyrillic, which is `sftt1095.pfb` and
`sfrm1095.pfb` in this case.
