Yes. The low-level openssl AES implementation (AES_ecb_encrypt(), etc.) is
available (see openssl/aes.h for the function declarations), but in most cases
it is better to use the EVP_* interface, which provides a uniform interface to
all of the crypto algorithms.
Here's a blog post with some sample code doing AES encryption with the EVP
interface:

It doesn't look like the low level AES functions have a man page, but their API
is similar to Blowfish's (see the man page for BF_encrypt(), etc.).
