Have you tried the QDBRTVFD API?  The docs for it state that the length
it returns for a variable-length field would be the max length + 2.
That seems to be what you need -- but this API is somewhat more
complicated to use than QUSLFLD...

DSPFFD is an option too... albeit, it's a slower, less robust option...
but it'll almost certainly take less time to code...

If QUSLFLD doesn't give you want you want, you'll have to do something
else...  The fact that the programs already using QUSLFLD won't save you
much if it doesn't give you the information you need :)
