(defun rcd-embeddings-create-for-llm-responses ()
  "Create and store vector representations of text responses from a
language model that lack existing embeddings.

This function interacts with the user to process log entries in `log'
table where `l.log_logtypes = 8', indicating they are related to large
language models (LLMs). It checks for missing embeddings by performing
an SQL query on database connection specified as variable `rcd-db'. For
each entry without existing embedding, it retrieves text from the column
named `log_description'.

Non-nil means that a warning message is displayed if no embeddings can
be created. Return t if successful creation of new entries in the
'embeddings' table occurs.

Important arguments:

- The database connection variable `rcd-db' must point to an active and
  valid SQL database.
  
The function uses helper functions such as `rcd-sql-list',
`rcd-db-get-entry', `rcd-llm-get-embedding', and others for
processing. It ensures that each log entry with a missing embedding is
processed, embeddings are generated using the LLM response text from
`log_description' column, inserted into database table 'embeddings'
along with their respective IDs.

If an error occurs during this process or if no valid embeddings can be
created by `rcd-llm-get-embedding', it issues warning
messages. Otherwise, a success message is displayed for each embedding
successfully stored in the database."
