I would not use a conventional point->polygon process because that expects your points to define the boundary of a polygon and it doesn't sound like yours do. It sounds like yours are hotspots that are somehow related.
However, there are lots of ways to create polygons for this sort of situation depending on what is sensitive in your data. Here's a few ...

I would perform both a left and right single-sided offset buffer on one of the linestrings and test if the other linestring crosses both sides of the offset buffer. You would need to use a suitable small buffer distance for your analysis.
For example, using Shapely:
from shapely.wkt import loads
def actually_crosses(A, B, precis=0.0001):
"""A hybrid ...

I think it depends.
ESRI's geometric library is similar to JTS, but you need to think about readability and maintenance.
Why do you need to check your geometries type everytime you pass them around? That is unnecessary and riddles your code with if clauses that do nothing. Java is statically typed, so, go ahead and use your types.
If you have a method ...
