  You have to tell us what you mean by "ran a Weibull model",
there are (at least) several different contexts in R in which
you could have done this (distribution fitting, survival analysis ...)
what packages/functions did you use?  Can you show us a reproducible

  logLik(model) [note capitalization] might work.
 str(model) or str(summary(model)) might show you
what's lurking inside the fitted model or its summary,
and allow you to extract the log-likelihood.
