It's not typical to use SOAP for AJAX calls, in fact I don't think
I've ever seen that. TBH, it's not typical to use SOAP at all unless
you are in the thrall of a tool manufacturer.

REST is all about objects, but this doesn't mean that you cannot do
RPC with REST, you just have to re-align your mindset. Instead of
calling a remote method, your REST call creates an object that gives
you the results you are interested in.

Eg, rather than calling a search service via SOAP to get a list of
items, you would create a SearchResults object with your arguments,
via REST. To access the results, you would use further REST calls to
examine attributes of the object.

The best way to architecture something like this is with a task queue
system like celery, creating a task to perform the search when the
SearchResults object is created, and testing/waiting for results to be
completed before returning data from attribute calls.
