I am in the process of making a routing engine. I want to know, is it possible for a road segment in osm data (that is accessible from pedestrians) to only be walkable from one way ? Or should I take from granted that every single road segment is double-way ?

Actually, look at this osm routing query. GraphHopper routing engine registered this edge as double way...

Here's an overpass query that shows that it's not too common:

Some routing engines will get things wrong; Graphhopper clearly has here. Some of the examples are a bit "open to interpretation", such as:
