which nearest controller can do it?

No, the STM32L1xx does not support crystal-less USB, as you can e.g. find in AN4879.

Unfortunately there is still a Copy'n'Paste typo in the data sheet of the STM32L152RCT6, according to which it should apparently contain this, which is not correct.

It depends on your requirements. Just have a look into AN4879.
