Every time I run a SEM, there is a loglikelihood for H0 and H1. For example,

Loglikelihood
H0 Value -13701.249
H1 Value -13697.746

What exactly are the null hypothesis and alternative?

The H0 model is the model specified in the MODEL command. The H1 model is the unrestricted means, variances, and covariances of the observed variables.

Usually we do not want to reject the specified model. Does that means we are looking for non-significant p values for the Chi-Square Test of Model Fit?

Yes.
