I have a couple of live edge slabs I was planning on making into live edge end tables but I'm wondering what to do with the cracks in the side - if anything can be done at all. Could I fill them with a glue/sawdust mixture? Would some other commercial product be better? Is it worth attempting at all?

Here are pictures of the cracks: Live edge slab

Could I fill them with a glue/sawdust mixture?

You can yes but common woodworking glue (PVA-type, white or yellow) wouldn't necessarily be the best choice for the glue.

A much more solid fill can be made by using epoxy. Filled (or just coloured) epoxy is now a common material for filling voids and defects in wood. To a degree this kind of filler can stabilise a crack and add strength, but without some further means to hold the wood steady (e.g. a butterfly key, hidden bolt or dowelling) a crack may continue to open up, so it is worth taking at least one extra step as a safety measure.

Further reading in some previous Q&As:

Large hole filler products, what is available

Seconding the suggestion to use epoxy. That crack is an interesting one though because it goes through the nonflat surface of the live edge, so its a bit challenging to make a mould to stop the epoxy from leaking out.

Epoxy pouring jig

My suggestion would be to build a mould that holds the slab on its side (with the live edge on the top), and pour the epoxy in from the live edge. I did a live edge slab project recently and built a somewhat similar jig for that purpose. In your case since the gaps are bigger I think it would be worth using a proper melamine mould (with vices holding it into the slab) to seal the crack on the flat faces.
